I just had to quote this. This pretty much sums up when I use mine for. When the iPad was first announced, I thought it was one of the stupidest inventions ever (my laptop can do all that and more) but when I first held one in my hands at a Best Buy, I fell in love. I take it everywhere I go. It's much lighter than my laptop, and the battery lasts way more than I need. It's useful when my wife wants me to drive her somewhere to go shopping. I'll just stay in the car and either browse CR or watch movies I ripped from Netflix DVDs (or steam Netflix, but I prefer having the copy on the iPad) or even read books with an application called Stanza, which is more open than iBooks or Kindle.
It's freaking amazing...I mean magical, sorry.
Oh, and Skyfire was just released for iPad. It can play flash video. I have it on my iPhone but have not purchased the iPad version yet. I rarely visit flash sites.
