I'm considering buying HD movies from iTunes instead of Blu-ray because it allows me to store everything on my computer instead of having to worry about physical media. I live in NYC so space in apartments is limited. I am hesitant because it is an expensive proposition. Who uses iTunes to buy or even rent movies on a daily basis? Do you find the 720p quality acceptable? I heard rumors that they are going to increase it to 1080p but that is a little scary because if I buy the movie now and they upgrade later, won't they charge more? The same happened with iTunes when they upgraded their tunes from 128kbps to 256kbps and charged $.30 extra for each song you wanted to upgrade. Yes I am aware of torrenting movies but I'm contemplating being a straight shooter and renting or buying from now on.
