I returned my Transformer. It was kinda tough, because I really will miss the microSD, micro USB, and mini HDMI ports on the tablet, plus the ability to use the most sweet keyboard dock ever.
I'm sacrificing a lot for the Galaxy Tab 10.1. But the Transformer did seem to have a lot of small annoyances too. Back was slippery. Glass was very thin. Tablet creaked a bit. Bezel was ugly. Felt a little cheap.
I'm going with the Galaxy Tab because it's lighter, something I value a lot in a 10 inch tablet, even small weight differences become noticeable over time.
The Galaxy Tab just looks a lot better. I don't mind admitting I care about the appearance of my tablet. Galaxy Tab looks sleek and elegant. Transformer looked quite ugly in my eyes with it's sharp angles and extra wide aluminum bezel.
Hoping the glass on the Galaxy Tab is thicker. I could push on the Transformer glass and easily see it bending like it was some cheap resistive display. Nothing like my iPad that doesn't bend at all.
