From Information Week: Windows XPP Significantly Outperforms Vista, Tests Show. “[R]esearchers ran a mix of tests comparing existing versions of the operating systems — the original Vista and XP SP2 — and versions that had been patched with the latest updates — Vista SP1 beta and XP SP3 beta. Tests were also run on machines with 1 Gbyte and 2 Gbytes of memory. Windows XP trounced Windows Vista in all tests — regardless of the versions used or the amount of memory running on the computer. In fact, XP proved to be roughly twice as fast as Vista in most of the tests.” (Emphasis additional) From when I purchased my first personal computer in the late 1980s, I bought a new system and upgraded operating system about every two years. It’s been four years+ since I bought a new desktop. I keep patching this Windows XP machine with new hard drives, fans, cables, and disk drives because the prospect of a spanking new machine with Vista is so disheartening. If this system melted down tomorrow I’d seriously consider buying a Mac and using Boot Camp to run XP.
