The key is that each new rendition of mobile device brings something new. Something different. This essentially causes the chances of success of these devices to increase. The Zaurus was a little better than the Palm, the 770 a little better than the Zaurus. So, it is to be expected that there will be new mobile devices that will get right the things the 770 didn't and couldn't. I don't think there will ever be a perfect mobile device made for everyone, but we will see many more mobile devices that one will easily find one or two that are just right for them.
