Not all GMA950
The Mini 10 models with the Z530 processor use a different chipset with GMA500 graphics. I have read divergent views as to which is "better", but for the "Hackintosh" crowd who likes to load OS X on their netbooks, they'll want to give GMA500 a miss. Given that the 10v is very similar in component choices to the 9, other than a slightly different audio chip, it seems likely that it will run OS X also.
It looks to me as if the Mini 10v is Dell's intended successor to the wildly popular (at least among users, if not reviewers) Mini 9, which still has demand outstripping supply.
