I think its very worth it, the remote alone is great.
I have quite a few HD-DVD films and the HD-DVD drive.
Its a "dead" format but they will still play and you can watch them.
It can be, depends on the quality of the transfer. I've found that the effect wears off after a bit though, so what once looked awesome just looks normal once you get used to it.
Thats the case with pretty much anything though.
Watching stuff at 1080p looks great at first but you get used to it.

How well do these things connect to a PC?
Apparently it's a **** of wizz.
Wish they had these kinds of prices at launch lol.
