I've had one for the better part of a decade, and yeah it does get uncomfortable after a while, the plastic spring tile back tends to have some undesirable points of concentrated pressure, and despite HM's claims of it being healthy to sit in, the seat becomes just as uncomfortable as any other when you've had your butt planted for a while.
Not long after getting it I switched to a configuration that lets me move near effortlessly between standing and sitting perched on a tall chair, with an 8.5" tall footrest on it and another forward, beneath the keyboard (which has to be sturdy, as it regularly holds a large fraction of my body weight). The tall chair is a no-frills dining table chair; it isn't comfortable for very long, but that's the point--built in reminder to move. I have been set back to the typical office chair/desk configuration a few times in the intervening years, and it never felt like anything but a step backwards. Some day I might try a drafting chair (effectively a tall office chair), to get another usable position between perched and standing; for the same reason, I backed the sitpack kickstarter for what is essentially a monopod stool, which will make 3/4 standing/sitting an option.

It is a survival imperative that monetary value be reimagined to significantly include the relative sustainability of the evaluated; that the objective of obtaining wealth become not just itself--which by definition guarantees nothing but obtaining wealth--but to prolong the survivability of Life, however indirectly. Such a transition would put the highest priorities on food, water, and energy security, construction of a space elevator (or etc.) + the colonization of space, and balancing ecological and geological systems. Major progress in these objectives would usher in a new era of commerce, technology, biology, science, exploration, and practically everything else. But there isn't a big window in which this more readily achievable; major suppressions on the horizon are life-like VR coupled with mastery of neural hacks taking soft control of wide swaths of the population (there's already quite a bit of success with far from life-like simulations), and the depletion of our freebie super dense energy supplies AKA fossil fuel. Until there are independently sustainable pockets of life separated by large amounts of space, our billions of years of toil and reproduction is at a very high risk of amounting to nothing, the inconceivable cumulative effort of countless organisms could be undone with a single unfortunate event.

Oh really? Because I have a Nexus One here which would disagree (if it were able to go long enough without crashing to do so). Running 2.3.6 and it will forevermore report itself as "up to date," because google decided the phone was too old to receive updates after less than 2 years.

I have no idea how much gas costs, my bicycle runs on doughnuts. The car has been in storage for more than a year and I haven't looked back, I'm healthier and wealthier than ever before.

I've owned/operated a makerbot for almost 2 years now and have gotten to know the company pretty well. I'm confident that they are headed for some serious trouble. AFAIK prior machines were designed without the input of a certified engineer (and I doubt that has changed), which meant that there were many very basic mistakes made: lack of static drain lines, absence of strain relief, operating components at or beyond the limits of spec, using cheap ATX PSUs for 12v instead of 24v bench supplies, etc. They were able to get away with this because their customers were hackers/makers who were happy to troubleshoot and tear things down, often without even contacting the company; I'm STILL putting in tons of work (at least 100 hours in the past month) trying to get my printer to be reliable, and even still mostly enjoying the process. But now they are obviously courting your everyday folk, presenting the machine as plug and play. I can tell you with a glance that the machine is likely nowhere near the complexity required for that much to be true, and can also say from plenty of experience that makerbot as a company has a history of using marketing as an excuse to stretch the truth into, well, lies; for instance, the Automated Build Platform of the ToM was presented as giving one the ability to run prints serially (which they were selling hard, and was the thing that sold me), but the feature was never even implemented on the software side. Not that it would have mattered, the ABP was a total disaster due to, surprise, design oversights and rapidly abandoned, to be replaced with a setup conceived by a user. If it weren't for the freely shared insights of Ed Nisley, an actual engineer (site: softsolder.com) and a handful of other users, makerbot's printers would still be just occasionally somewhat reliable. The reality is that 3D printing isn't ready for everyday folk just yet at ~$2k; the closest small printer from a well established company is the Stratasys Mojo and it costs $10k. So my guess is that makerbot will succeed in getting less technical customers, and then severely suffer the consequences, compounded by having lost to reprap a good share of the customer base they built selling kits. Also, I should point out that as usual makerbot is severely lagging, that there are many far more exciting developments (well it's not hard to be more than essentially none) going on in the open source printing world. My new printer is a reprap (mendelmax, really dig the rostock though), and I'm sure it will put the replicator2 to shame.

Sorry, I forgot to mention trains. And yes, some things will still work best with fossil fuels (i.e. farm equipment) until a sufficient alternative is found. The point is that using energy more efficiently will have a much greater effect than using marginally more efficient vehicles. There's just no sense in using tremendous amounts of energy to move several tons of metal and 4 empty seats everywhere you go, especially considering that more than half of all trips are within 3 miles.

I have discovered the solution! This miraculous machine is the most energy efficient form of transportation ever invented, it's so simple a child can repair it, and everybody loves to drive it. Not only that, driving it actually makes you healthier, encourages friendly bonding between strangers (i.e. society building) and naturally reinforces the local economy. It's called a bicycle.

Motor vehicle accidents are the 4th greatest cause of death in the US. If you restrict the age range to people under 40, it is the greatest cause of death.

About a year ago I decided to ride a bicycle every possible trip. This decision has had a profoundly positive impact on every aspect of my life. This week I rode a bike 35 miles up a mountain, along with all my stuff for a week of family vacation; the next day was spent mountain biking. After all this I experienced no soreness. When I started driving my bike, I thought that I could never sell my car, at most I would put it in long term storage. Now my car is a really expensive and unnecessary burden, driven barely once every few months.

If we seek to optimize efficiency, safety, health, and cost, the car of the future is actually a bicycle.

...compared to the rate of growth of everything space related after the construction of the first space elevator. The way I see it, every rocket that isn't on a space elevator building mission is a waste of time/money.

I'm a USAmerican and while I'll admit to sucking at math, I think it's a stretch to say I suck "so badly." I'm not exactly sure what The Problem with America Today is, but if I had to guess I'd say a lot of it has to do with extremely large organizations motivated solely by profit (AKA news media) manipulating the international discourse in ways that are profitable, which has nothing to do with a sane representation of reality. It's probably not even that satisfyingly conspiratory, unfortunately, but I do know that I've never seen anyone ram together a few legitimate data points like I have in this blog post (which I'm reproducing in entirety here to save everyone the effort of having to click through to a foreign environment):

Godel's completeness theorem proves that mathematics is infinite, that is, no collection of mathematical rules and structures can ever be called finished or complete. There's no reason to assume that includes expressing emotion, epistemology, etc., especially because it is known there are different sizes of infinity, but it is clear that math can express an awful lot. Of course there's plenty of reason to conclude that math can't say much about something like ontology, because questions like "what is really real?" (as one of my many philosophy books puts it) are so terribly ill defined that they evade even rudimentary logic.

I'm supposed to be doing my analysis midterm right now. The part I'm at requires that I prove (-a)*(-b)=ab, and I have only the slightest idea how that's going to happen. I fear that my course isn't being taught well, because so far it seems all I've learned is that I'm terribly afraid I don't actually understand any of this thing called math. This is rather disturbing, as it was only a few months ago that I decided I'd pursue my PhD in pure mathematics. Formal proof is indeed very important, but the class in which I first saw the potential was Philosophy 101, introduction to formal logic. It was only through continual reinforcement in classes such as discrete math that I realized the true power of logic. That said, for me one of the most enlightening moments was the revelation that all life is composed of (potentially) trillions of cells.

By most standards it's not a car, I was just tired of being ignored the moment the word bicycle was used. Obviously this didn't work as I was instead immediately modded irrelevant then flamebait, both of which not only confounded me but also deepened my fear that humanity is Screwed (despite considering myself an optimist). The car I was referring to is indeed an electric assist bicycle which receives somewhere short of 50% of its power from my legs. Though the electric conversion has been blowing my mind and that of the few intelligent people around me, I'm already ready to cede that a century of brainwash has made irrefutable fact of the notion that any distance further than across the street, or any cargo greater than a candy bar, or any weather at all requires a car. As such, I've begun the design of a four wheel, two seat electric assist velomobile just shy of a Miata in stature, with the intent of tricking people into thinking it's a car.

If I get hit by another 60 lb car, neither of us are likely to be seriously injured, especially if neither of us are going over 40 kph. It's very basic physics, if you're in something that's over 1300 kg (like the average sedan) traveling over 40 kph, any accident has the potential to be deadly. This is why there are on average over 3000 deaths per month due to car accidents in the US. Just because there's a tradition of high speed heavy vehicles doesn't mean it makes sense or is the optimum form of transportation.
