A couple Android related things... I am not sure if this is unique to my tablet (Acer Iconia A100) or is indicative of other Android tablets as well:
1) Battery life & Power Management: My iPad (1st Gen) can last for a 2 or 3 days with moderate use without the need for a charge. It also holds a charge if it sits idle for days or weeks on end. (e.g., leave it in a drawer at 50% power, and a week later when I wake it up, the charge might read at 40% or higher). On the other hand, my Android tab requires a recharge after ~5 hours of moderate use. What's even more puzzling is that if I let it sit idle, it still burns through the battery surprisingly quickly. (e.g., I could leave it with a 50% charge, and when I wake it the next day, it may be completely drained the next afternoon) I've tweaked the power management settings to turn off wifi when the screen goes to sleep & keep my brightness set to an almost unreadable 75%
2) Charging: I plugged in the charger for my dead tablet this morning only to notice a couple hours later (when I tried to power it on) that it had not been charging because I had not pressed the power button after it had been plugged in. On my device, it appears (I must be wrong on this) that you must press the power button (which will then display a red LED) before charging can begin.
I think Android has a bright future, but things like this will turn people off, especially if they are coming from an iOS environment. Maybe some of this is a manufacturer implementation issue, I dunno. Anyone else getting iPad-like battery life from their Android tablet?
