So all of a sudden I looked up and I noticed I have a nice large white wall as I am facing it from bed. Instead of looking at a screen or having to get up and sit down to look at a larger screen, why not just stay in bed and controll the "wall" with my magic mouse or iPhone There are HD and regular projectors. I am imagining using mobile mouse to walk around my room controlling the projection on the wall, using it to controll programs while editing, or for watching movies and YouTube. I remember going to Frys Electronics and seeing some for about 400-700 dollars. But I don't know if they were HD. Do I need HD? Or for such tasks will standard def work well on the wall? I think it would be convenient to spend only 300-400 on such a convenient tool if it works well but if it's not an option and everyone thinks HD is a minimum for desktop resolution and visibility then I would be willing to spend more. I have a bed stand and it would be perched up behind me on the bed frame facing an open wall about 15 feet away. It's not far so the picture could be sharp and semi close? In have a 2011 MBP that I would set next to it and plug it in and then run in clamshell or however it works and use my iPhone 4 as my mouse pointer pad. Can anyone give me some background and recommend some good deals on projectors that will look good enough projecting a MBP 17" desktop?
