Good to read.

I just had to deal with sending my 360 S back. I was very pleased with the whole process. It didn't cost me a dime, and it took 2 weeks to the day from start to finish.
My games played great, in game, but the video cut scenes were choppy as hell. I got it back Monday and the videos play normally now.
Enjoy your new toy, when you get the HDD. (You can use a USB memory stick until then should you have one.)
