It's only a matter of time before Google joins the party with their Android adaptation, Wether that's a good thing or not I don't know but ReMix is getting there, which is an android spin-off. As soon as Google get's this right and releases a good hardware solution together with good software support for apps like Office, Photoshop, Lightroom and others a like they might get it of the ground.
I'm kinda on the fence on the idea but after the initial adaptation pain I think this might actually be a good think. FCP and rMB optimization seems to prove that it's not always the specs that determine user experience. I'm no expert so I can't say for certain, but I'm just wondering if existing apps can be optimized better to run more efficiently? Then it would justify the future of PCs being mobile hybrids.
