I've used an Aeron for a while, and it's great. But last weekend I bought an Embody chair by Herman Miller, the same company that makes the Aeron. Night and day difference.

The Embody was designed for people who sit at computers all day. It forces you to sit with good posture, which may sound painful, but it's damn comfortable. And healthy. There's basically no way you can comfortably slouch in it.

It's spendy at $1600, but this is your long-term health you're talking about. Bite the bullet.

This technology isn't particularly new -- telehealth has been around in some forms for a few decades, but it's definitely taking off now.

One of the benefits not mentioned is that, in addition to 'remote monitoring,' telehealth services generate a huge amount of useful data for clinicians. Our telehealth program collects weight, blood pressure, pulse, and (for diabetic patients) blood sugar readings daily. It takes less than five minutes for the patient to do these tests.

In turn, their physician and care team have daily medical data, and can detect subtle changes much more quickly than a weekly nurse visit or occasional office visits. The only other setting where you have daily vitals monitoring is an in-patient hospital or care facility; now we can have it in people's houses. And the patients generally love it -- they feel a sense of security knowing that their health is being monitored.

I suspect many of the misgivings about remote-wipe policies have to do with the clarity of explanation. Explain to users clearly what ‘remote wipe’ means, and what they can do to protect their data.

Just today, I wrote a new document for our users about our remote wipe policy and how, with iOS 4.2, they can too thanks to Find My iPhone. Here’s what I wrote, under the heading ‘A brief but important note about your privacy and data:’

“It’s important you know that the locating feature of Find My iPhone is tied to your own, personal Apple ID. This feature is not accessible by anyone else in the company, including the IT department, and cannot be used to track or determine your location. We respect your privacy.

“On the other hand, the IT department can immediately erase your iPhone’s data should it be lost or stolen. This would cause everything on your iPhone to be erased, including pictures, music, and apps — not just company data. Therefore, we recommend you connect and sync your iPhone to iTunes regularly to ensure that any personal data on your iPhone is backed up.”

Companies have a right to secure their smartphones —there’s a lot of data on them. End users have a right to protect their personal, non-company data. These are not mutually exclusive. Can we agree?

The OLPC XO was very easy to use, yet somehow Sugar/Linux doesn't get the same sort of attention Mac OS X or iOS do.

What real-world questions did the OLPC XO answer? I've never used one, so I honestly have no idea.

For as many people as bought the various Apple products, Macs in the XP and Vista era answered the question, "Would you like your computer to not be a malware-infested heap of frustration?", the iPod answered the question, "Would you like to carry all your CDs in a fun little pocket-sized box?", and the iPhone answered the question, "Would you like to carry the Internet in your pocket?" Not really novel stuff, but it was packaged thoughtfully and it made sense to a lot of people without requiring a great amount of explanation. The iPad is arguably the first major Apple product in a while that doesn't immediately scratch an obvious itch. Its selling point is more along the lines of, "A lot of what you do with your computer, in a smaller, sleeker package."

Again, I don't think it's rocket science. Apple built what their own people thought would be great, and lo and behold, a couple million other people thought it was great too. Sure, Apple is a slick marketer (although Apple's marketing budget is in line with other tech companies its size: http://tech.fortune.cnn.com/2009/10/28/apples-2009-ad-budget-half-a-billion/) and gets a lot of free love from pop culture, but it would be myopic to suggest that this is much more than sugar-coating on an already solid and aggressive business model.

Go back about five years in the archives of most tech publications and you can find similar stories about "The coming onslaught of iPod competitors." Look how that worked out.

For some reason, the tech community believes that the commoditize-and-cannabalize cycle that typified the 1980s and 1990s is a perpetual law. It isn't, and Apple's success this decade is a resounding rejoinder to that view. Apple's products aren't, in all respects, better than the competitors; what they are is more polished, more refined, and an order of magnitude easier to pick up on and figure out on your own.

The typical screeds about how Apple's success is due to marketing prowess, reality distortion fields, media sycophancy, etc. are all a bunch of red herrings. Apple makes great products, and it's a real shame that more companies haven't picked up on how they do it and why. It's not rocket science to diligently refine your products while at the same time planning their long-term placement growth; it's just more involved than most companies want to be.

So sure, I'm sure there will be an onslaught of cheaper, different tablets that mindless consumers (Who, I might add, the tech community still believes to be largely ignorant about technology. You know, in 2010.) will buy up and the iPad will be dead. It's impossible that, say, every single one of the competitor tablets will be inferior in one or more significant ways that fails to make an appreciable dent in the iPad's adoption rate. Equally impossible that Apple would refine the iPad beyond its current iteration to entice new customers. I mean, really.

I'm not giving Apple the keys to the kingdom carte blanche, as heaven knows they've made their share of mistakes, but on the whole, I think they've been too successful, too visionary, and too aggressive to continue this endless narrative about how, just when they're about to succeed, the commodity tech market comes up aces and wins the hand.

I'm assuming you're talking about web video; if not, this info won't be applicable. The 'Video for Everybody' project at Camen Design has put a lot of work into cross-platform HTML5 video, and the test page has an extensive compatibility matrix for both desktop and mobile platforms.

Be aware that if you're targeting Android, its implementation of HTML5 video is lackluster (for now; I'd expect this to get better soon). Details of the problems, and a few solutions, can be found here: http://www.broken-links.com/2010/07/08/making-html5-video-work-on-android-phones/.

I'm speaking purely for the United States here. The first thing that came to mind was this great scene from the movie Apollo 13 where engineers are told they have to fit a square filter in a round hole using only the elements on the table. First reaction? They dive right in.

So to use this as an example, it sometimes feels like we've lost the raw brilliance and creativity that allowed us to put human beings on the moon. And we did it years before the development of advanced composites, sophisticated integrated circuits, and computer modeling. The moon missions were calculated with slide rules; even the astronauts had to be skilled mathematicians.

In that sense, it feels like our creativity is on the wane. On the other hand, perhaps it's just changing form.

True, we haven't put anybody on the moon in a while, but we've instead built a giant worldwide interconnected computer network. We've built a search engine that aggregates and indexes it all. We've built touchscreen devices that can make phone calls, access websites, pinpoint your location to within 30 feet using satellites hundreds of miles in the sky, and put it all into a tiny package that slips into your pocket and runs all day on a battery charge.

That's pretty creative, and it's showing no signs of slowing down. So I don't necessarily know that we're less creative today; I see the emotional and anecdotal evidence for it, but the contrary evidence suggests that we're still exceptionally creative and eclectic with our skills.

The list should more accurately be called, "Top 500 publicly-acknowledged supercomputers." You can go right on thinking that the US NSA, British MI6, and even some private industries (AT&T?) don't have vastly larger supers that are not publicly disclosed.

If there's one thing history teaches about rumors regarding upcoming Apple products, it's that nobody talking knows anything.

That's not always the case; sometimes, far from it. The source for this information comes from John Gruber over at Daring Fireball. It's well known, and John says as much, that he has sources inside Apple. As a reliable critic ('critic' as in Ebert, not hostility) of Apple, it seems his sources are either known to the company and the leaks are green-lighted, or else Apple simply doesn't care enough about smaller announcements to ferret out the mole. I'd bet heavily on the former.

John doesn't always make predictions of a declarative nature, but when he does, you can more or less take them as stated fact; for example, his "predictions" for last year's WWDC.

Name an important piece of investigative journalism done by the Times in the last ten years. I can't. And I'm a regular reader.

So am I. Here's a recent example: Toxic Waters, a series that ran late last year. The Times put a lot of time - and thus, money - into researching the series, combing through the data (and filing the FOIAs, etc.), as well as the interactive features, which were well done.
