ASUS Transformer - Survey says it da bomb!
From an admittedly small sample size (me, the owner, and about a dozen friends, colleagues and associates who have had some "hands on" time with the device), the verdict is a resounding HELL YEAH that a tablet which can dock/transform into a netbook is a perfect compromise/hybrid.
I myself used to enjoy browsing the web on my partner's iPad, and the eeePad is a world of productivity apart from that very passive media consuming fruit slab.
I don't think much can be drawn from "sales falling back" of the Transfomer since launch - that happens with just about any new device... an initial rush which slows as more reflective and considered purchasers choose to part with their hard earned.
And the decision to part with hard earned is also becoming harder... the success of the iPad was perhaps as much a result of it's launch coming at the end of the most recent period of consumer optimism, and the relative lack of success of more recent tablets equally perhaps attributable to the new era of consumer fear and pessimism.
