Hi Koenimga,
Thanks for this post - It sounds like you are doing well with the pk101 - your points pretty much highlight that first generation of pico projectors - alright but not AMAZING. certainly awesome for the size of device though - a little miracle. Just think how good its going to be with 3rd and 4th generation pico projectors, MVIS could bring out a HD Laser pico projector before you know it! its going to be amazing.
800 x 600 is liveable but is it not downscaled in the 101? in newer generations this shouldnt be the case - I cant wait to see full hd pico projectors.
HDMI is the way forward for these devices - everything will spit out to hdmi - ps3 to pico projector? yes I think thats a good idea. Couple that with my little portable loudspeaker and you have a mobile gaming rig - pretty cool stuff eh?
If you get a 301 we would love to hear a review of that - maybe with some photo's? we can stick it on the homepage so it helps people make more informed buys of pico's for themselves!
cheers again for posting!
