I know a lot of people use wee-PCs at the gaming table. Today, via Lifehacker, I found EeeRotate. This is a tiny program that does one thing. It sets up hotkey combinations to rotate your screen by 270 degrees (and back). Suddenly, your netbook can be turned sideways and you have a full-page display for viewing PDFs.
This was designed specifically for the EeePC, but it should work with any PC. If works just fine on my HP Mini. I showed it to Angela and she asked me how I liked my new Kindle.
