And ThumbEE was in turn deprecated by ARM v8. I don't know if anyone ever used Jazelle or ThumbEE much? >> Even though it's difficult to compare CPUs I think that showing a 3D >> game performing well is an indication that the device has adequate CPU >> performance for most workstation tasks. > > In a general sense, yes. > > But AFAIK graphics is heavily FPU-bound (floats) where systems tasks are > heavily ALU-bound (integers).

Look at the Raspberry Pi -- it can do high-res video decoding just fine, but that is no indication that it is at all fast at general stuff. (It's so not, despite what anyone tells you). I've used multi-core ARMv7 systems and they're pretty useable at the sort of speeds that Chromebook runs at, so I reckon it would probably be OK for the target purpose of xterm windows and some light browsing in Chrome. But as others have pointed out.. it's going to be a fight to run Linux on it, and I suspect as much as it'd be good to have an ARM laptop I just won't want to be spending the time to make it work reliably.
