I be in the tech field and I have be wait for the pico projector to come down in price . I just never expect one of this quality and feature set to sell for under $ 300.00 . I have look at the 3M one and some of the other but none come close to this 20 lumen switch blade of a Pico projector . I get mine about 3 week ago and I have be use it constantly . everyone who see 's it be like `` I be so get one of these '' . I like the fact that it come bundle with the cable require to connect you laptop . with other unit this be extra as well as a case . I purchase the IPOD connector kit so I could hook up my Iphone . it look awesome with video come from my Iphone . please note that the extra battery in the Ipod\/Iphone connector kit be for the pk101\/102 projector and will not fit in the pk201 . so bascially I 'll ebay that battery . the Arcsoft media software I be not so happy about . I try convert a video to the pk201 profile setting in Arcsoft only to have it not work on the unit . if I convert the same file utilize Arcsoft 's pk101 profile -lrb- lower video bit rate -rrb- then the file will play on the pk201 . I have a support case open with they about but its really a Arcsoft issue . I have work around that anyway by utilz other software to do the job . long story short be that I have do a lot of research regard the Pico Projectors , this be by far the best due to its brightness , input capability , resolution , and ability to play content on its own -lrb- build in media player -rrb- . those be some of the most important thing to I when I be look for a Pico Projector . do I also mention it utilize Micro sd so I you can have up to 16gb of storage . it be great just take this unit out without have to hookup any wire and play a movie or project a powerpoint . I have never write a review before and I hope this help you in select a Pico Proejctor . Cheers
