A Widescreen Laser Projector In Your Pocket
Edis Krad writes "Redmond based company Microvision is in the last stages of developing and releasing a portable, laser-based projector, code-named 'Show WX.' The projector has a resolution of 848 by 400 pixels (WVGA) and, since it uses laser-scanning rather than LCD to form the images, it does not require a lens to focus, allowing it to display images virtually in any surface. The device comes with its own user-replaceable battery, which means you could take it with you anywhere you want. Although there is no pricing information on their website, according to this local news video, it could cost at least $200."
And project an image of my ass onto a car window as I pass someone?

Because you're sitting on a goldmine if it can.
What? It can't? *sigh* Oh well. A man can dream, can't he? A man can dream
My work here is dung.
Are you just happy to see me?
Particles, stuff that matters.
$400 to $500 USD according to the manufacturer site; not $200. Dang, $200 would have been awesome.

Now I can project even more realistic UFOs on low clouds near the airport!

... are the two limitations of small projectors. They claim 10 lumens while most conventional mains-powered projectors are typically 1000-2000 lumens. That makes the product usable alone in a darkened room but not much of anywhere else. Their claim of "movie capable" battery life rather than a specific time period leads me to conclude that they watch shorter than average movies.
I predict that, like the pen scanner, this proves to be a geeky cool but practically useless device.
This has been done before, IIRC Samsung released one of the first TV quality raster scanning system for laser shows.
Basically a standard laser show setup uses multiple lasers (to get your RGB) combined into a single beam then passed through a device, such as a PCAOM, which acts as rather like a programmable colour filter. (this isn't the only way it can be done with solid state lasers).
Two sets of mirrors can be steered in the X and Y axis to draw your shapes, beam effects, etc.
In the case of a TV or other raster displays the beam is steered much like you would an electron beam on a regular TV. It scans a horizontal line, moves down scans across, repeat. You can switch the direction of the scan (left to right, then right to left) on alternating lines to speed up the scan rate.
Wikipedia has some info on Laser TV's in general: http://en.wikipedia.org/wiki/Laser_TV and LaserFX has some info on PCAOM's if you're interested in the older tech: http://www.laserfx.com/Backstage.LaserFX.com/Archives/Archives6.html
Early systems actually used multiple projectors overlapping or drawing the first 3rd, 2nd third, etc of the image to make up for slower scan rates.

NoNoNoNO!!! Bad Xpeter, Bad boy. Do you realize how fucking annoying this is going to be? PowerPoint presentations everywhere. Is that the kind of world you want to grow up in?
Faster! Faster! Faster would be better!
