To me the ipad is the wrong choice.
Things Apple don't play nicely with other file formats, and other devices.
I have a Nook Color which is essentially a tablet. It's sold as an e-reader but it does so much more. The Nook Tablet just came out and it's only $250
Check out each one and look at the apps available see what you want.
I am partial to Android because it's not picky about what it works with.
A friend of mine has an ipad and she does not like it because Apple is so propritary with their files and all. And they do not have flash player. Steve Jobs did not like flash player therefore Apple products do not support it many websites depend on flash player.
