Woohoo...

This is one of the easiest softwares anyone can use. Here are the few pros and cons on this software.

Pros:

1. Innovative - I do not know any such software in the market.
2. Super fast - You don't even know that your face is recognized and it unlocks your screen. Cool
3. Very less/No help required - At the most requires a 50 words documentation
4. Small Download and quick install - ~1.8 MB installation package size and takes ~30 seconds to install
5. No restart required (This certainly is the best thing with this software.) - Integrates with Windows Shell (it is basically a password protected screen saver) even without a restart
6. FREE - greatest value for money anyone can get

Cons:

1. Face recognition does not work as correctly with spectacles on. So, I've to remove my spectacles for it to identify me correctly
2. Crash dialog appears when it locks PC
3. Help actually contains license information - Kind of weird, but luckily it does not require any help.
4. Does not work in multi user scenario. This does not allow multiple enrollments. If we need to add one more, we have to delete the existing one.
5. Less administrative features (settings) and no image correction features.

In spite of these cons, I'd give it a high 8 out of 10 for this software (Remember, this is still in its beta). Meaning, I recommend this product to everyone.

Ever since touch screen came into the picture, there has been lot of attention amongst the technical crowd.

Its not entering into every arena of computing with touch phones, later multi-touch screens and the newest surface computing. Seems like this is not going to slow down any time now.

The latest news is the Microsoft research is busy developing something called double sided touch screen. This is not multi touch with just two touch restriction ;). In fact, you can touch the both sides of the screen.
