I previously did a review on the AAXA M2 micro projector paired with my acer aspire one. At the time I thought that it was the best combo out there, but now that AAXA technologies had made a pico projector that is 80 lumens and battery powered I think this is the new bad boy in town.
With the acer aspire one being only around 10x7" and the aaxa p4 pico projector only 5x3" this would be an ultra portable combo.
Some bigger magazines like mobilemag have started reviewing this product and gave it some good reviews.
I may have to get one even though I already have a M2. I know aaxa sometimes has promotion codes so I'll probably keep a look out for those.

this thing is really nice combo and my friends are always impressed by how bright this mini projectors can be.
