The MiLi Pro is a LCOS, LED-driven projector for the iPhone and iPod Touch. Simply pop your iPhone into it and it can put a screen up on your wall.
It's got a 640x480 resolution, so it probably won't look all that good at 70 inches, which is why they recommend 40 tops. Also, at 10 lumens, you'll be lucky to get 30 inches in a dark room.
The whole thing is rechargeable and has VGA and RCA inputs as well as a dock connector. Look for it to drop in September. [PhoneSuit]
