I couldn't handle not having access to my Xbox for more than a day. :) So I went and picked up an Arcade model... everything switched over and I was up and running. Funny thing was, it came with a bunch of arcade games that I had never bought... so I found myself playing through Feeding Frenzy and a little Pac Man championship edition. That sort of ate up my night and didn't leave much room for Trials HD.... but I did get a little time in.
Only bummer about the arcade model is that it doesn't have the chrome disc tray like my Pro model did... maybe I can swap that out?
