I am tempted by an iPad but it's bugging me that you don't seem to be able to drag and drop files from a PC.
Why do you want an iPad rather than an Android tablet?
Is it because they look pretty or is there some functionality you can only get with an ipad?
I bought a cheap 7" Android tablet a couple of months ago (should have been £110, I got it for £70) and I've been surprised how much I've used it. I thought I'd just take it with me when I go out, instead of taking my netbook, but I use it a lot around the house too.
The 7" size means it will still (just) fit in a pocket, but it's much easier to browse the web and type on than a phone.
