No one is being killed by the 5v on the USB bus. The problem is the counterfeit chargers are often poorly designed and can fail in a way that shorts the USB cable to the AC power.
There was an excellent teardown & analysis of a cheap charger last year that pointed out serious safety issues.
Recently they added the ability to also buy the audiobook version and the app *syncs your place* so you can switch between the two formats. That's a pretty amazing idea.
But the app doesn't help the author. He said he had a Nook. Thanks to the recent firmware update people with a Nook Color or Nook HD can get then app, but if you have the eInk based "normal" Nook, you're just out of luck.
As DRM goes, Amazon has done an excellent job of reducing annoyance. They don't try that "you can only read this book on 2 devices, ever." stuff that we've seen elsewhere. But I get the feeling the only reason Amazon's DRM is so unobtrusive is they were so overwhelmingly powerful they could force publishers into a relatively consumer friendly system. We're lucky Amazon cares more about selling books than trying to wring money out of Kindle hardware sales, or the DRM would have been a lot worse.
The video says that the wind is manually entered by the operator. I find it odd that it shows the temperature and barometric pressure. Is that really useful information when you're lining up a shot?
After watching their little YouTube clip, I wonder how useful this is. Placing the aiming dot seems really similar to aiming in the first place, I guess the only difference is you don't have to compensate for gravity/etc. I found it conspicuous that they didn't show their simulated target moving in the video. Can this only help with a stationary target? It seems like it would screw up your aiming if half the time you had to do it manually (compensating for everything) and half the time the system handled it.
