ReadyBoost
Vista can transform any spare USB flash drive or SD card into an additional memory cache. To use the ReadyBoost feature, simply plug the drive into a spare USB port (or insert your card into the slot) and when AutoPlay kicks in, select Speed Up My System. You can specify how much of the available memory it should use. Any noticeable improvement in speed will largely depend on how much memory you have installed in the first place. Lower-spec laptops will probably benefit the most.
ReadyBoost isn’t available for XP but there is a decent alternative in the shape of eBoostr (www.eboostr.com). This commercial product costs between £12 and £20 or there’s a free trial version you can use for up to four hours at a time.
