SideWindow Transforms Your Old PDA in to a Second Display

PDAs have gone the way of the dinosaur, they don’t even have good eBay resell value. So in the age of smartphones, what do you do with that old Windows Smartphone laying around that is still in great condition? Instead of transforming it in to a paperweight, you can use it as a secondary display. SideWindow is a neat app that allows you to transform your PDA in to a secondary display appropriate for small windows like a buddy list, a to-do list, or whatever else you might need to glance at frequently but you rather not waste precious screen real estate on. The app retails for $24.95.
