Nowadays everyone has a flash drive. The prices for USB drives have fallen dramatically in recent years meaning it's now a good time to replace your old sluggish drive. But why would you want to do this? Well, with the release of Windows Vista and Ready boost (enabling you to use Flash Drives as RAM); the transfer speeds on many drives has increased so transferring your files will be quicker than ever. Also, programs can now be installed on drives, enabling you to run Email Clients, Office Tools etc all off of your USB stick.
