It wouldn't be the holiday season without us offering up some free goodies for our readers, so many thanks to Federico Carnales for his participation in this giveaway.
LauncherPro -- one of the most popular replacement launchers for Android, and one that I use exclusively -- provides for a ton of customizations to your home screen. With LauncherPro, you can apply custom icons, use up to seven home screens, tweak your app drawer settings, add up to 15 apps or shortcuts in a scrollable dock, and much more. I've tried several home replacement apps, and some may offer more in terms of customization (re: themes), but LauncherPro's silky-smooth animations and UI are what keep it installed on my Evo.
Head into the forums and post in this thread for your chance to win.
