Blu-ray and Hi-Def are the same in the way that Plasma and LCD tv's are the same. They are the same, but they arent. They are pushed by different companies, and eventually one will come out on top.
Right now, Toshiba, I think, has a laptop out with an HD-DVD drive in it. I've search high and low, and have yet been able to find an HD drive for my computer. I found a review for an HD-DVD drive for a desktop, but the drive itself hasnt been release, made by NEC.
I'm also going to wait, unless I can get a relatively cheap player... I just got an HDTV a few months ago and have yet to watch anything HD on it... I cant wait.
