Speed up your PC with USB pen drive on XP

Speed up your computer with a spare USB thumb drive with eBoostr, an XP-only application that brings the benefits of Windows Vista's ReadyBoost feature to XP. The app can work with up to four devices, up to 4GB on each, and its smart-cache feature gives speed boosts to your more frequently used apps and data. eBoostr could be perfect for XP users who want a little extra memory but don't want to install RAM themselves, or even for laptop users who've filled every free slot. eBoostr comes as a free trial version, which gives you four hours of functionality each time you boot up, or you can download it's full version from here Download
