I'm sure Nokia has gained a lot of experience over the past two years dealing with Linux that the MID providers don't have. We all make assumptions that whatever they produce will not have any problems, no update issues and perform flawlessly just like the UMPC did I think it will be hard to beat TI with processor efficiency Mhz for Mhz. x86 compatibility allows more applications to be used "off the shelf", but probably wont be well integrated unless time is spent on the UI - the one thing most Linux distributions fail to do well.

Also I think the MIDs will be competing for the same dollars (along with other MIDs around the same price). By the time these come out the N810 will be $350 USD if not cheaper. The N810, NXXX might be the easy choice because maturity, UI, price and performance (as a function of battery life and speed).
