Side by side comparison of 3 pocket projectors:

o Optoma Pico PK101 DLP 480x320 pixel resolution , rated at 11 ANSI Lumens, and

o 3M MPRO 110 LCOS 640x480 pixel resolution, rated at 10 ANSI Lumens, and

o IMITO M100 Multi-Media Pocket Mini Projector LCOS (claimed) "640x480" pixel resolution, rated at 20 Lumens.

I ordered one each of all 3 to see which was best. Turns out the Optoma and 3M units are just amazing. Granted they don't throw any more light then a LED pocket flashlight (which is what they are), they, in a dark room (which is what they are for) do an amazing job.
The Optoma is definitely a little brighter (as you can see from the photos) and the colors are more vibrant, but it also tends to over-do the colors a bit, often giving a greenish tint to gray scenes. On the other hand, the 3M unit has less contrast then reality, but the color is good if not a little too suttle (Vivid colors in real life don't appear very vivid.)
One advantage that the optoma has over the 3M is that the 3M projects straight out, so if you set it on a table, half the picture hits the table. The optoma projects upwards so the bottom of the picture is just above the surface of the table.

The IMITO, however, is a little bit of a sad story. It's not 20 lumens, but is dimmer then the 10 lumen 3M unit.(As you can see in the below photos.)
And it's not 640x480 resolution, either, as you can see by the below photos: It adds jaggies to diagonal lines like the 480x320 Optoma does, and like the true 640x480 3M unit does not.

The ebay seller who sold me the was very kind and said he'd basically make it right, but he wanted me to send him some photos - so I figured why not do a nice quicky review while I was at it, to be a help to others!

Furthermore, the IMITO unit also suffers from burn in: If you pause your movie for a few minutes with a high contrast scene, then resume playback on a low-contrast scene, you can see the burn-in ghost image of the scene that was displayed when it was paused.
The IMITO also suffered from significant dimess around the edges and corners. It would make a great hobbiests toy if it were $50. (As it is, I paid $250 for it -- which was more then I paid for either of the other two...)
So how's that for pretty funny? Otherwise, the IMITO unit is very cute, although you can hear the fan running inside.
(The other two don't have fans.)

So, without further introduction, here are the photos with brief tags below them:

Above: The IMITO Unit. Model No.: M100. Input: DC 5V,2A. Made In China. FCC. It also comes in red and black. Mine is the silver.

Above: My test setup. From left to right: Optoma, 3M, IMITO, all connected to the same video source. You can clearly see which one is brightest and which is least bright!

Above: Comparison number 1: The blue screen with the onscreen menu from my video camera. This shows which is brightest, and also which has more jaggies. Also notice the fading around the edges and corners.

Above: A better picture of the difference in resolution between the true 640x480 3M unit and the lessor resolution of the IMITO unit. 3M on top, IMITO on bottom. Notice jaggies in the right-pointing triangle. There's no way this unit (the IMITO) is really 640x480 resolution.

Above: Comparison number two: Actual video footage I took of a seagle flying about: Again, clearly the IMITO is dimmer then both of the others, even though it's supposed to be twice as bright. The color is a little bit less washed out, however.

Above: And the burnin/ghosting. Depending on your monitor, you may not be able to see it. But look for a faint white ghost of a burd above (and another one below) the actual bird.

Below are a few more pictures of the IMITO M100, in no particular order, and serving no particular purpose..
