I agree fully with any other OS, but I'm surprised that it's even possible to get Windows 7 in on less than 40 GB.

I don't believe that for a second. I have an old machine with Win7 on it, and Win7 ate 50 GB of disk after installation. Mac OS X Lion eats much less - I haven't checked, really, but I'm guessing around 10 GB of disk, tops. Of course, linux can eat as little as you want, depending on what you install. At any rate, 120 GB SSD is fine both on my Macbook Pro and on my arch linux box, but would be a disaster on a windows machine.

Ordered mine recently, took 2 weeks from farnell.

Quit using them in your teaching. Graphing calculators are the work of the devil. Kids spend a lot of energy learning something that is obsolete when outside schools, spend money on an overprised product (you can get a much more powerful netbook for the same price, ~ish), and wind up not learning how to do math by hand. That way, you'll stop finding old ones, too.

Oh, and obigatory xkcd.

Depends a lot on the field. There are probably a lot more errors in medicine than in physics.

This is a great idea. You know more about memory problems than most people - maybe you could also consider making an app that's useful for rememebering things? I'm sure the regular TODO apps out there are missing out on what the needs of the handicapped are.

You can't be too rich, too thin, or have a too big stick.

They've actually got their own flavor - Scientific Linux CERN (SLC). Most annoying distro I ever used, but that's another story.

Why isn't this modded funny rather than insightful?

I've spent a year at CERN and, indeed, they do use windows. For secretaries and administration, mostly. Man, I hate their whole windows admin regime (you've sometimes got to dual boot into Windows to fill out a form). Linux is being used for all sorts of technical purposes - control centre, simulation servers and desktops, low-level control stuff, etc. Windows is only used for powerpoint and "typewriter" kind of work, as I expect is the case elsewhere.

I was wrong - they're up to 14 simultaneous materials, at least: http://www.objet.com/Objet%20Connex350/

There are printers which can mix materials out there. Not sure if they're up to 3, but certainly not far from it. Also, I'm not sure if anyone is planning to take on the toaster industry; their mass production is probably more efficient anyway.

Right, so I have an arch linux box, too. pacman > App Store, for so many reasons I can't begin to list them.

I don't disagree as such; however, I don't see the point in speculating over all sorts of conceivable future scenarios. In my book, the App Store, which requires signing and sandboxing, is a good idea in the same way that signed packages in your average linux package manager is a good idea - as long as there's an option to overriding that by manually downloading a program. If apple kill that option, it's going to hit them hard in the dev community, so I'm not betting on that happening anytime soon. These possible scenarios are certainly not proof of apple's evilness NOW.

I've got mod points, but I'll rather point out that on my mac I often compile and install software that has never been approved by anyone. Mac OS X is unix, so ./configure; make works rather often. I'm not a "fanboi" but I'm not too impressed by claims not supported by facts, either.
