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.
Apple have announced they have sold over one million iPhone 3GS through Sunday, June 21st –the third day after its launch. Meanwhile six million users have downloaded iPhone OS 3.0 in the five days since it was released on Wednesday last week.
The company notes that the original iPhone took 74 days to hit 1 million in sales.
