Windows XP SP 2 VS KUbuntu

While most of us still facing hardware problem with Windows Vista, we must think to prepare our computer hardware to be ready installed with Windows 7, the next generation OS from microsoft. If you think to consider use Linux rather then Windows, still you need to find the best Linux Distro to run well in you old computer hardware. You can't run the latest KUbuntu in your 128 RAM while you still can run your Windows XP SP2 in your 128 RAM but your system run very slow.
