What makes you think that the use of people who have this drive is limited? I play many games myself, I've installed tons of software on my computer, and have used this drive for reading cdr and cdrw discs with no problems, with the newest firmware. Yes, the drive has been buggy, but like I have said before, I have had no real problems with it, even with all the use it has had. Now you may say that well the drive shouldn't need a firmware update every 5 weeks, which is true, but there hasn't been a firmware update since last August, I think they finally have the drives problems straightened out.
I'm not some Kenwood freak, I have their 42x TrueX drive and it's a piece of crap. Yes, you may have problems with this drive, but you also may not, it's a chance one has to take. There are the advantages like the fact that the drive smokes all other cd-rom drives, including things such as ripping audio, in wich I've been able to rip at 32x.
Kenwood was trying to be innovative in the cd-rom industry, and deserves some credit, it's the future of cd and dvd media if we are looking for faster speeds, unlike other solutions like the piece of crap 52x from Creative.
