Many top runners do not run this way.
It took me about a month of a few runs per week (20-30 mins) to adjust -- so not long at all. One of the mistakes I made at the start was going too far, too fast: I tried to do my usual 1h+ runs straight away in the Vibrams and was pushing-off from the ground, concentrating on staying on the balls of my feet. Bad idea.
Anyway, here's some tips from someone who has been through it:
---------------------------------
- Relax, relax, relax.
- Don't push off from the ground, rather, concentrate on lifting your thighs.
- Don't aim to balance on the balls of your feet. You're not running on tip-toes, and that's going to put insane strain on your calves. Instead, get the general area of the top half of your foot to land first, almost flat-footed is fine.
- Aim to tap the ground with your feet about 2-3 times a second, as if your feet are going in a circular motion, and passing by the ground. It's like you're incidentally propelling yourself along with gentle touches to the ground.
- Keep hips relatively low, legs relaxed, leaning slightly forward. If your calves start to hurt, then relax more.
- You will get sore calves as your feet and leg muscles get used to the new style of running. Stick with it, and don't overdo it.
How thick are the soles? If I step on a nail or broken glass, will it penetrate the sole?

The soles are really strong, but I wouldn't rule out a perfectly aligned spike or blade (scalpel tip or something?) going through -- but to be quite honest, something like that would probably damage a traditional running shoe; protection isn't a substitute for looking where you are going.
Because it was such a great, joyful experience (and I still didn't get new laces), I've continued my barefoot runs. Yesterday morning I ran 10 miles (6 miles brick sidewalk, 4 miles sandy forest path), without any problems whatsoever. You do have to watch out for broken glass trough, so when I go between dusk and dawn I put on my aqua socks. But otherwise, I've found my bare feet to be incredibly resilient and wear-proof. Also, I am running completely pain-free for the first time in years. It does require some changes to your stride, most importantly not landing on your heel. But not being constrained by rigid running shoes anymore, your body is able to figure out the rest as you go.
In a few weeks, I'll be running the half marathon in my city. The self-conscious part of me wants to wear shoes and avoid the questions and strange looks. (You will get those, anything from people shouting "Hey, you forgot to put on your shoes" to others nearly walking into trees and lamp posts while staring at your feet in amazement.) But the Dvorak-typing, trackball-using part of me just want to do what feels best, regardless of any social standard, and go barefoot: zero pain, maximum joy.
- I don't have to periodically pick it up and reposition it because of running out of mousepad room. (My wrist doesn't like doing that, and my sister -- who has had surgery for carpal tunnel syndrome in both of her wrists -- says it's bad too, but I couldn't find an online citation.)
- I can press the buttons without accidentally moving the pointer at the same time. (This is mainly a problem with ball mice, but I've gotten unintentional pointer movement with optical mice too.)
- I find it easier to do things that require pixel-level accuracy with a trackball.
I prefer the Logitech TrackMan Wheel, whose trackball is thumb-operated:

i got physical pains from reaching the mouse
Instead, I've found this more comfortable: http://www.evoluent.com/vmouse2.html
Works great with a gel wrist wrest on the mousepad.
(You are talking about the kind for divers? I also have them for kayaking. And I've always been very careful with walking on stones, etc.)
Do you mean the kind of new "shoes" they discuss in the article?
I feel like listening to a chef discussing wine and then ask about the color of his shirt. :-)
But going barefoot allows my feet and toes to flex freely and feel the surface. I am able to use parts of my feet and legs that used to be constrained by my running shoes (most notably my arches and calves). Because of this, my running gait has changed a lot. After years of pounding the pavement (striking heel-first) I am able to run smooth and easy, and it feels great.
Thanks to this new running style, there is hardly any wear to the soles. I think they will last around 500 miles. After that, I'll just spend $10 on a new pair.
I found some of the statistics in the book to be really interesting. One guy researching bare foot running makes some sort of offer to pay anyone that can produce a single peer reviewed scientific study that shows that running shoes reduce the rate of injuries or make people faster runners. There are none! Think of all the crazy and only moderately applicable studies that have proven even the tiniest of facts while the huge assumption that we need running shoes has gone unproven!
It's just not fun to jog at 9 minute/mile pace.
As for shoes, wouldn't worry about them. Best runners I've met (sub 4:30 mile) use Nike and Asics, and I haven't noticed correlation between shoe size and how good a person runs. A much bigger correlation usually appears to be between person's gut and how easy he or she runs :)
There's quite a good formula that Pete Riegel came up with to predict your speed over a certain distance: T2 = T1 x (D2/D1)^1.06. There's a caculator on this page: http://www.runnersworld.co.uk/news/article.asp?UAN=1681. It's been pretty accurate for me, YMMV.

And NYMag did a feature on shoe tech (comparing Masai, Nike Free, Vivo, Vibram) before the Ferris hype: http://nymag.com/health/features/46213/index1.html, much more in-depth than the Wired article.
In any case, track and field athletes have always, and still do, wear paper-thin shoes with spikes.
Anton Krupika, who has absolutely dominated ultra-running events over the past few years nearly always wears minimalist shoes, if any at all.
In fact, he ran one of the toughest and most competitive trail races in the world in 10 ounce racing shoes a couple of years ago... and won by over 3 hours! It was the Leadville 100, a 100 mile trail run on hilly terrain at an elevation averaging over 10,000 feet:

It seems like there are a lot of articles lauding barefoot running but not a lot of barefoot runners - at least in the US. To me, switching from my Asics to bare feet is asking for trouble after years of heel first running. The switch would require months if not years of slow and steady adjustment, which I don't think most people have time for.
It's also worth remembering that not everyone has been running heel first for years. Most of them haven't been running at all.
I have not tried barefoot running yet (maybe at the beach for a start). But you seem to assume that running shoes have an advantage on hard surfaces, remember that there is no evidence to support this. I am sure it is more demanding for the skin under the feet if you run complete barefoot tough.

1. Google "POSE Running". The site has lots of information and drills for changing your form to accommodate a mid-foot strike.
2. Consider transitioning by using racing flats instead of immediately going to barefoot/Vibrams. Or get both and run in the flats but do all your walking around in the Vibrams. This will allow you to gradually strengthen your feet, ankles, and calves.
3. Start on grass with short distances, focusing on form.
Also I've noticed walking around the house barefoot for a day or two will make my knees hurt.
