Since Sony Clie pdas aren't being made anymore

What other pdas have built in thumbboards like the sony clie ux40 and ux50? I have a ux40, but want to get another pda. I love the clies, but sony isn't making them in america anymore, and one problem I've had with them is the memorystick MAGICGATE. MAgicgate stops legit programs from playing too sometimes, so I want to get a pda that has a thumbboard and looks sleek like the sony clie models, but that doesn't use memory sticks. SD Cards are good and the other memories.

Any suggestions?
