I don't get the iPad either, maybe I'm a luddite, but I don't feel the need for one. I certainly wouldn't spend £500 on one, I don't think I'd be happy spending >£100 on one either. I don't much like typing on a touch screen either.
I've got a big laptop for my main computing needs and a netbook for when I'm travelling, Slingbox, browsing etc, I suppose if I really felt the need to surf the net while on the bog then the netbook would do the job.
I've got an Android phone and that's fine for what it is, but do I want a bigger one that doesn't do a great deal more or I can't do on my netbook? Nah.
