I just did a quick scan of the pdf and didn't see the thickness, I might have missed it though. In pictures it looks very thick, and with a platter drive I'd have to assume it won't be anywhere near as thin as the ipad2. Seems like the portability of the ipad2 and some of the newer android tablets is contributing greatly to their success and I'm not sure how popular a chunky tablet will be in today's era of sleekness. I could understand and possibly accept a chunky windows 7 tablet, but a chunky ios or android tablet has the seal of death on it IMO.
To put it mildly, the iPad is to thick for my taste, and the iPad 2 is acceptable. The iPad 2 should have been one smart cover thinner.
Other tablets range from acceptable to ridiculously thick lol
