Right now I don't think you have to worry. So many companies are using XP that MS will continue to support it for at least 2 more generations of a new operating system release.
Right now there is only one generation out there and that's Vista and companies are just not upgrading.
Hi, stockjob. Have you considered building your own? I didn't know the difference between a power strip and a power supply when Bruce Thompson on Dream Machine helped me build my first Terminator. It was fun, I learned a lot, and I got a topnotch computer at a great price. Think about it.
