The definition of a MID, a mobile internet device, changes with every person you ask but one thing remains constant. It’s aimed at the consumer and not the productive professional. That’s ultra mobile PC territory! Consumer devices require careful attention to ease-of-use and fun, dynamic software so the choice of operating system becomes just as important as the hardware it’s built on. Shanzai have a nice article up today that covers most of the options. I’d add Maemo to the list and remove any reference to Windows desktop operating systems but it makes interesting reading. At the moment it looks like the ARM/Android combination might take the lead in the 2010 market but as Moorestown and Moblin for handhelds feeds in, the choice might get tougher. One thing is certain in our mind though, if you can’t tailor and personalise your device with applications and widgets, it’s going to be a boring experience.
