I just set one up for a friend. The thing is lightning fast, was watching bluray movie off the drive through hdmi on a sharp aquos 42 and playing modern warfare demo on the pc, and the bluray did not skip. The game was a little slower than usual though. Still very impressed. The WIFI is stronger than I expected, was getting a superb signal in an area where my other notebooks usually drop.
The things that I did not like:
-Asus did not pre-install in RAID. The OS is on a 120GB partition and the other partition is 340GB Data on same drive, the other drive is butchered into two partition as well. That gives you 4 drive letters, what a mess. Need to reinstall to take advantage of the raid features. Pain in the ass.
-No USB 3.0, right now not a big deal, but 2 years from now this will be a problem.
-No BluRay Player bundle from Asus, had to download Cyberlinks PowerDVD 9, runs great, but its a demo.
-The mouse that comes with this thing is wired, come on Asus! WTF?@# 3 extra bucks is that much of a big deal?
-No remote, ok I knew that, but since the mouse is wired, it makes it a further hurdle if you are using it to watch movies in the living room and have the pc next to the tv. At this price I would think they would include a remote. (Luckily my friend still has one from multimedia Asus she bought 4 years ago)
Conclusion:
Thing still kicks serious ASS and I would buy one if I had the coin to spare.
EDIT: BTW, there are (TWO) 2 X 500GB (7200rpm) drives in the G73JH-A1.
