Re: Samsung: "blu-ray has 5 years left"
Shaw Cable (for cable tv) does a on-demand movie service, some of the movies are HD. The bandwidth doesn't count towards your internet cap.
Shaw Cable (for internet) has a monthly cap of 60gigs (aggregate), which is enough to grab a number of HD movies off (as a example) xbox live (HD movie sizes are ~5gig).
Note: Comcast has announced they are capping at 250gig a month.
As for digital distribution goes, I'd love to move from cd/dvd's to that, if I could only find the stuff I want to watch in my region. eg: I like some British shows that are not availible here.
