EnGadget has in-depth coverage of Intel’s Ruby PC.
Built-in wireless with Windows Vista (complete one, not CE version).
Note that this device is a prototype, and Intel has not been very good with pushing consumer electronics. I was at Intel Developer Forum 2001, when they showed off their wireless Web tablet in San Jose. Yes, at some point Intel indeed had a wireless tablet that had a larger screen than Nokia 770. The engineers showed it to the reporters and press, but any question regarding release date or pricing was met with the excuse “We’re just engineers, we don’t know that marketing stuff”. Not too long after that Intel Consumer Electronics division was shut down, and Louis Burns, who never liked me calling him Mr. Burns (Simpsons reference), now runs Digital Health.
