One problem with using USB to charge it is that while I know that the USB ports on my computer don't provide the kind of juice you'd want for that, there will inevitably be users who don't. Give 'em a power brick that only plugs into the wall the tablet, and it's just about foolproof.

But it’s not a laptop, it’s a tablet - looking at an ipad, or a Samsung galaxy - they both use USB plugs and an AC wall adapter like I linked. But they use their own crappy proprietary plugs at the device end. With Ipad it’s not too bad as it is popular enough that you can buy cheap aftermarket cables (as in your not forced to go to apple for it) and the USB wall charger is useful for other things/devices, but with both your buying cables that have one purpose and while I have not looked too hard Samsung ones may only be reliably found at stores that sell the galaxies and usually at a 457694503% mark-up. That is absolutely the case for the now defunct Motorola Xoom table. A wall charger with a tiny little prong that plugs into the device. The aftermarkets I could find carry concerns that they would not work or could even damage the unit and in my mind one plug that I have to carry around with me is stupid when it’s not necessary. It was simply an attempt by Motorola to force y9ou to buy from them. (I don't own any of the above devices but I use them at work)
With my personal phone (HTC desire) or a Asus transformer prime for example they use Micro-usb plugs at the device end and came with a AC wall adapter for USB cables and I bought more and have one in each room of my house that makes sense to me and one in my car, in case Im on the road or at a friends and need to plug it in... cost me nothing really as I could buy it all at monoprice.
Dealing with all these proprietary plugs at work has led me to the very simple conclusion - never buy a device with proprietary plugs.
As for you concern for stupid users er I mean people not knowing they can't charge off their laptop, I would assume the manual would tell them how to charge their device, if they fail to read it or are too dumb to remember, my heart does not bleed for them. Frankly I could care less. The stupid will always find a way to be stupid.
