Speak for yourself. I don't have a PC monitor actually. Both my PC's are hooked up to the 40".
Honestly watching Rocky on BD is so much better than going to the movies (I watched a marathon while the most recent one came out) HD sound, HD video without dealing with the assholery in cinemas. I really think this will signal a major change in how cinemas do business. For 2 people to go out and watch a movie is around $50 for tickets popcorn and drinks, not including parking and travel expenses.
But yes not a big deal for most people here, 720p becomes necessary around 30- 32" and 1080p at around 42". My old man was asking me to buy him a HD set top box for his 29" CRT. Had a hard time explaining that HD woouldn't mkae a difference as his TV was only SD capable.
From my understanding most recent film is a hell of lot higher resolution than 1920x1080 (I think it was arounf the beginning of this century or around that time). I remember reading it was something like 3 or 4 times 1080.
