Oh my god, this thing is amazing. I had no idea how cool it was! It has EVERYTHING the iPhone has, without the phone part and no kind of extra service fee. I mean, seriously. It's awesome. I can check my email, get the weather, watch YouTube, get directions, surf the web, listen to music, etc, etc, etc. Wow, I'm amazed.
If you are an educator or a student, and you buy a Mac, you get one. FOR FREE. Do it!
