I have a device like this. It is in my pocket when I am at work and at my bedside when I sleep. It is my iPod. It has a non-Windows operating system and a non-traditional user interface. It has a ton of applications, and around half of them need the internet (is that pronounced "c-l-o-u-d" now?) It has more than a few games, which seem to consume a similar amount of user-lifetime-hours that the fancy graphics intensive games consume.
It runs google apps - I can edit google docs, and see google maps, and check out google earth. I didn't know I wanted one until my wife gave it to me, now she might divorce me because I love it more than her.
Although not perfect (can't print, devoid of flash games, typing could be improved), it proves that there is a market for the kind of handy internet appliance that keeps being advertised as the Next Big Thing.
My point, and I did indeed have one, is that this market cares less about OS features than the average reader of /..
