One of the best uses of ReadyBoost is on a notebook, where memory is expensive, sometimes hard to install, and there are not as many memory slots as on a desktop. ReadyBoost is not a replacement for additional system memory but it can help out, especially at times when your system could use more memory. The only problem with this is keeping a USB drive hanging out of the side of a laptop is a surefire way to create a problem- either by the drive catching on something and being ripped from the socket, the system being pulled to the ground after getting snagged on a passerby, maybe just getting left behind when moving your laptop from one place to another. Luckily there is solution.
