I remember when I had the original Eee PC that folks were asking me about the eBook reading experience was. Specifically, folks wanted to know if I rotated the display orientation from landscape to portrait so I could hold the netbook like a regular book. I never found the need to do that but for those that do on an Eee running Windows XP, you should be able to rotate the display using the Intel graphics software. Unfortunately, that solution doesn’t rotate anything else, meaning that your touchpad is still configured for standard, landscape usage.
EeeRotate is a bit of freeware that tackles both issues as it handles rotation for the screen and the trackpad. Ideally, I’d love to see it handle remaping of the arrow keys as well, but for now, it’s strictly the trackpad from what I see. Since so many of today’s netbook components are the same or similar, there’s a good chance this will work on non-Eee devices as well. In fact, TeleRead found a related article showing how EeeRotate works just fine on a Lenovo S10 as well. I still have Windows 7 on my MSI Wind so once I finish with that and get XP running again, I’ll give this a try. I’m not sure I personally have many use-cases for it, but if you, this freeware is right up your alley.
