Rumor aside, I'm surprised in general that ARM's stock has risen so much in the last year. I suppose the increase in price is due to the current, and anticipated, use of ARM designs in mobile devices. Still, in the long run would ARM really be able to maintain it's lower-power chip dominance over Intel? I know Intel isn't there yet, but they seem to be a fearsome R&D competitor.
