SSD prices are dropping so quickly that it makes more and more sense to have one in your PC. 120 or 128 GB versions you can find already for £90, and for less than twice that you can buy an SSD with double the capacity. It will still take a long time before SSDs will rival traditional hard disks in terms of price per gigabyte, but the cost has gone down enough that it's becoming more common to use them in higher-end PCs. With good reason too, because upgrading from hard disk to SSD will make your PC feel faster more so than a faster processor or more RAM.
