A few days ago we talked about the Samsung Galaxy Tab and why we don't think it's an iPad killer. Somewhere on the list we talked about the size, saying it was much smaller than the iPad, but too big for a pocket.
We stand corrected, it does fit in a pocket (About :33 seconds in).
Aside from that, we actually like the commercial. Unlike Motorola's Droid commercials, it shows everyday people using the device for things that are actually practical. No T-800 arms here, folks!
