Just after I dropped a bundle on a 20" cinema display to go with my 15" PB 1.5, my film editor friend evilly suggested that for the same $1200 I could get a video projector and use the nearest white wall as a monster second display (in addition to all the other cool things you could do with it: Watch TV, DVDs, etc.) . I do some video editing and it would be great to screen footage on a huge wall in one of my rooms that has no windows. I have another friend who does this, sits in bed with his laptop and wireless mouse/kbd, using his bedroom wall as his display. Anyone else doing this or think it's worth it?
