Came across with tiny 10cm x 10cm pico projector on sale for about £200. I didn't expect too much but wow this really performs. At 200 lumens its plenty bright enough for powerpoint and also for movies etc. I have at old Runko CRT that is about 100x heavier but no clearer. The projector can be carried in a laptop bag and allows inputs direct from sd card, hdmi and d-sub. Impressive and highly recommended!
