Yes, I returned it.
Back in this thread I was pretty excited to have one, my head brimming with the possibilities! Within hours, I had figured out how to convert and play video on it, and then word started to spread about how to hack your home wireless network to allow you to surf the web. I even learned how to put e-books on it in a mostly-readble format.
Besides the hacks, the screen was gorgeous, and even the bundled Spider-Man 2, one of my favorite movies of the year, definitely added to device's value. I almost never got tired of watching Spidey and Doc Ock duke it out atop a Chicago elevated train (yes, Chicago - I saw Sam Raimi filming on the El with my own two eyes). But what about the games?
