Just got an iPad 2 (not the Retina display model) on Friday and LOVE it! Except it keeps giving some kind of "alert" every now and then like it's some kind of notification but no notification messages are appearing like they do on my iPhone! It's a pretty, chime-like sound, but I wish I knew what it's trying to tell me!
Light bulbs you shouldn't buy
There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
