My understanding is that the only really viable choice on the market at the moment is Apple's i-Pad. But getting one of those involves tying your self in to the Apple system (as with all Apple devices).

Having just bought an Android phone, and having compared it with a friend's i-phone, I'm not convinced that Android devices are yet up to Apple's standards.

So, if you don't want to buy into Apple I think that the only thing to do is to wait for the next generation of Android/Windows tablets - which can't be far away.

Having said all that it doesn't answer your question, "do I want a tablet?" I want one - but I'm not sure that I actually NEED one!
