Best buy coverage; Wifi; Charging
Best buy coverage:
In my experience, it doesn't work out the way they pitch it to you. Back in 06, when I was still a PC (ha!), i bought a laptop and bought BB coverage. You have to take it in 3 times for the same issue, give the "geek squad" an opportunity to fix it 3 times, and on the 4th time you go in for the issue, they'll fix it. And at least back then, it didn't cover drop damage, etc. Maybe its different now? Better to get coverage under your home/rental insurance co which will sometimes cover electronics, imho.
Wifi:
No problems with reception at all - full bars (possibly better reception than I get w/ my iPhone 3GS around the house).
Charging issue:
I have no problem charging when its hooked directly to the computer. However, I hooked it initially to my USB hub (unpowered), and though it will charge, my iPhone dock (hooked to the same hub) stops charging - I get a "this device does not support charging" message until I unplug the iPad. I think I prolly will get a powered USB hub adn hopefully it'll resolve it (just so my desk looks nice w/ no wires protruding haha)
