Check the link below for some tablet observations
As of now, I’ve been carrying the Samsung Galaxy Tab for a month, using it every day; this has included two major road trips. I suppose there are a few other humans who’ve had this much hands-on with a 7" form-factor tablet, but I don’t know of any others with a blog and a free hand to write what they think.
My experience with an iPad is much less, but non-zero. Also, anyone who hangs out in cafés in Pacific time and scores upgrades on a few international flights has lots of chances for iPad field observation. (Early finding: On airplanes, iPads are used for reading magazines and playing lightweight games.)
