It’s become pretty clear at this point that scaling a smartphone OS up, rather than scaling a desktop OS down, is the better approach. Someone had to stick their necks out and try it. Microsoft tried and failed to scale Windows down, but Apple has apparently succeeded going the other way. Let’s not forget that the outcomes were far from obvious even as recently as a few months ago. HP getting on stage with Microsoft in January was their throwing in their lot with the desktop approach. I think they’ll ultimately come out happier having reconsidered. It actually took corporate chutzpah for them to cancel the Windows 7 Slate after showing it.
It is a stopgap, at best. Someone needs to take the time, do the research, and do the work to write an OS for these devices instead of trying to patchwork add and remove bits and pieces of systems clearly designed for other purposes.
You may be right, but remember: shipping is a feature, and, IMO, the most important one.
