How much do you want to spend?

If you're looking at the top end of iPad price range you can get some seriously capable stuff that goes beyond tablet level performance. Check out the Lenovo Ideapad Yoga and the Samsung Ativ Smart PC.

At the lower end, everyone is going to be happy with the tried and tested iPad, but truth be told its likely that they're on the decline due to the restrictive way they go about their business vs the freedom Android grants its developers/hardware manufacturers. Its already happened with the iPhone.

I had an iPad from work for a while but i sent it back recently as once the novelty had worn off i found myself doing everything on my Android powered Samsung phone instead. I just got sick of being told by the iPad i either wasnt allowed to do something or i had to pay for it.
