This form factor is perfectly sized to slip into a purse. As I've noticed anecdotally, users of netbooks in coffee shops tend to be skewed towards the female persuasion. But smart tablets will slip into any kind of bag, so they could be popular with either gender.
So the first question in the minds of OEMs, as they choke on the margin erosion from netbooks, is "do I build one of these?" I'd propose asking the question a different way, "what if I don't build one of these?" Mostly because my instinct is that others will. Loosely paraphrasing Intel's Andy Grove, either you eat your own lunch or someone else will.
But what can an OEM do to continue the netbook/notebook momentum and keep at least some sales from being displaced by smart tablets? For starters, they might want to think about adding a video-in port which can receive video from an iPhone/iPod/Android/Windows Mobile/etc device. And/or offering smartphone companion software so that the netbook can be used as a bigger screen and real keyboard for the smartphone. That would allow for a person to keep a pocket sized smartphone and have their notebook usage model.
I would think it a good idea for netbook/notebook chipset vendors to integrate such an input port, and keep the BOM costs down for OEMs. And I think Celio is set up nicely for a CES award.
