I played around with my library’s AppleTV and I learned some things.

1. The battery in the remote can die even if it just sits in the box most of the time.  This can be confusing when you try to get past the “Setting Date and Time” phase of the starting up process and you need to change the network you’re on and you can’t because the darn thing won’t respond.
2. You have to pay the $60 to get a decent HDMI to VGA adaptor to work with projectors. You can’t hack together $3 HDMI/DVI cable to a DVI/VGA cable  (May be obvious to most people but I seem to have to learn things the hard way).
3. Update software for  both AppleTV and iPad to get full functionality.
4. The dudes at Fry’s can’t test your AppleTV remote for you without a big manager dude present.
