I looked at the Kodak myself, but in my case Grandma doesn't have wireless, or internet for that matter. Got it for here many years ago, and found the PC it was hooked to hadn't been turned on in 6 mos.
So, a Wifi based solution isn't going to cut it for me. Chumby is out too.
Shame that T-Mobile's thing died, though some quibbled at the cost. Still it was absolutely self contained, having a phone number you sent pics to.
I sort of wonder about something like the Kindle Fire. It doesn't have a phone number but I believe there will be a 3G version. Maybe some enterprising Android programmer could set up a 'frame' program that pulls picks off a facebook or flicker album.
