You cannot get a demo for Portal 2, and if there were it would be on Steam as Valve (the creators of Portal 2) distribute all their games there exclusively.
However, if you haven't played the first Portal game I would recommend it, and if you like it you'll be sure to love Portal 2!
No. That would not happen since its been on the market for a long time now. Plus just go buy the game it is really fun
No, Portal is for PC only. Portal 2 is for PS3,Xbox 360,and PC. Plus it would suck on PSP.
Portal 2 comes out on April 18, 2011.
Buy IT! Well there is a site from where you can download many free full version games. (Farm frenzy 1 & 2, both are available there!) They have no time limit, and no demo (It's written on the site itself!)
No Portal 2 is for PC, Xbox 360 and PS3.

The only way to get Portal for free is by illegally pirating it via certain sites. (Which I think that is a really, really, REALLY bad idea...)However, you can get a demo called Portal: The First Slice on Steam...

Valve has announced "Left 4 Dead 2" at this year's E3 convention. It will be released November of this year. You can now get the demo from the Steam site. Google Steam and make a FREE account. You only have to pay if you buy something. Then download the demo. The demo is online. Very fun.
