The Internet:
The Internet is faster than I expected, despite the small frame and thin build. If you were going to surf the internet I would suggest using one of these.

During the time I was on it, the internet signal held out quite nicely, though youtube videos would not load. But, considering I was across the classroom from the router, I would say the internet worked very well.
Tips and Tricks:

There are few limitations such as the absence of certain programs, but all together the iPad can do anything a computer can.
