have the pk201 for about 3 week now . 4 1\/2 star . the brightness have much improve . I love that I can now connect just about anything to the pk201 . hopefully the rest of the cables\/adapter will be available soon . battery life be poor , at about a hour . but I mostly keep this plug in all the time . I wish the screen be just a little bit bigger . 70 '' easy with good clarity . the focus wheel be much better , not loose like previous model . Great for travel and hotel room . even with some light ambient lighting you can see the picture fine . best with complete darkness . \*\*\*\* Update \*\*\*\* after a lot of use I have notice a few thing when compare to other pk model . first the projection screen on the 201 have a smaller footprint on the wall . I be unable to get the entire screen to focus . area remain blurry no matter what . 101 have better focus . get the pk301 , really impressed with that model . bought one myself .
