In my mind:
For surfing the web: iPad > netbooks
For reading books: Kindle > iPad
For surfing the web: iPad > netbooks
For reading books: Kindle > iPad
So what to buy? I currently own a netbook, and while I like the device, for longer ebook reading and surfing, having the keyboard part is impractical. And I don't want Kindle, since I do a lot of reading in the dark room, and don't like the external lamp solution.
Overall, I am finding iPad to be a kind of product I'd like to have, but will probably buy similar alternative with Win7 or Android/Chrome OS.
