Without a doubt, one of the most interesting pieces of hardware3 from a design and form factor standpoint has been the Padfone from Asus. We first saw the dockable smartphone/tablet way back in May of last year as a concept device, but over the last eight months it's been steadily progressing to a retail release. We saw refreshed hardware at CES under glass, but rumors pegged it for a final, official unveiling at Mobile World Congress. Considering the invitation we just received to Asus'  press conference, we'd say those rumors can be put to rest.
