You know, I just upgraded my VHS collection to DVD lol... I'm holding off on BD now for the time being... I'm still using a SD television so I won't really see anything that I can't already see on a DVD lol...
The only HD display I own is my computer monitor (which coincidentally the only BluRay Reader I have is in my computer). My roommate has a 62" LCOS HDTV but it's running everything SD as well (no HD connections period).
