i've worked on a sony pc, and it's not worth buying like any other pre-built pc. the best thing is to build your own if you know how. the sony pc i've worked on was probably back in the beginning of the pentium3. I've also upgraded other peoples hp and those are worst than sonys. even now when reading the prices and the parts that come with pre-built pcs, the price aren't even a bargain in most cases.
