I'd rather not have low-res (comparatively), space hogging, overpriced, drm crippled downloaded media.
I'll stick with HD-DVD and Blu-ray. Give me REAL media that I can hold in my hand.
Realistically, IF downloaded media ever becomes big, there will always be a niche market for higher quality media like HD-DVD and Blu-ray (such as the type of people who frequent avsforum).
