DVD for me, it's all cost really, and on a 19" monitor DVD looks fine to me when I'm sat back a little from the screen, I can't see myself going to blu-ray unless it dramatically drops in price or i come into posession of a fortune. On a nice 1080p screen it does look excellent, but you need that screen in the first place. Also the analysts are correct, I believe one of the main factors that puts people off is lack of titles, pretty much anything can be had on DVD nowadays.
