Yeah, I got the HD DVD drive for the 360 in January 2007. Only had my PS3 since December 2007.
Only buy BRAB now, not bought any HD DVRAB in ages. May have a look for some bargains though, now it's dead.
Yep, the upscaling is great isn't it. My PS3 is my main machine for media - DVRAB, BRAB, divx, etc.
As I said, I'm not going to bother re-buying all my HD DVRAB on BD, but there are a few I think it would be worth it for (at least to avoid the noise of my 360!). Batman Begins is certainly one of them, & The Matrix when it comes out.
