Yes, exactly! Except with telephony and 3G support. :)
You can get it with a 3g datalink built in. Telephony, sadly, not yet.
Yeah, I noticed the 3G support after posting that. With 3G, though, Skype might be enough... I'm now seriously looking at this thing. Google produced some worrying posts and news articles, which may dissuade me, but if not, I may well buy one shortly.
