I had been using my iPad for browsing more than anything else at home, but since the combination of iOS 5 making it a bit slower/buggier and Lion making my MacBook a lot better I've been using it less. Now I use it mainly for content consumption, which it's pretty good at, and work stuff.
I'll likely eventually buy another one, but not the next revision. It's a fantastic device, but I hope to get some years out of it as it is.
