I went back and got the 60GB because my router is on the other side of the house! A wireless adapter alone would be at least $60, not counting the hard drive or card reader.
You're right, the free games are nice. I've downloaded almost every one.
The PQ was a bit better than I expected, but still not as good as the A1. I haven't tried any VC-1 titles to really compare.
I still have my A1 with 2.0 and love it. I've never had any real problem with skipping. Only scratched rentals have given me trouble.
