The upcoming Maemo6/MeeGo phone could be it for me, as I need to have as many funtions as possible stuck into a single device. This business with the Pads and Slates is taking it in another direction completely. If the next NXX device is thinner with a 4" screen and qwerty then I'm sold.

That said, I do feel a strange yearning towards a tablet shaped device as well :P My ideal tablet would run either Ubuntu or MeeGo.
