I'm thinking about a possible home entertainment setup and it appears that a projector may be my best bet given the layout and small-ish space. I don't know too much about projectors today, other than that the 1080p alternatives are EXPENSIVE. Can anyone help fill me in? What are the advantages/disadvantages of going with a 1080p vs. say a 720p? Will I notice THAT much difference? I'm not a videophile. Doesn't have to be amazing, just good. Will probably be hooked up to a mac mini and used to watch movies via dvd, bluray, and netflix streaming as well as streamed TV from the web and downloads. Any help would be appreciated!
