I was testing the Developer Preview of Win8.
I plan to put Win8 Public Beta on my laptop.
I always put Beta OS on a dual boot configuration on my laptop, which I use as main OS.
The reason for this, is that if I need to re-install, or uninstall to put Win8 official or newer beta, and something goes wrong.. I have significantly less data, and programs to worry about,
