“Windows XP is hardly on it’s last legs.”
Not now but it will be. I would not be surprised if MS stopped updates to push Vista very soon.
One thing I recently discovered about Vista. I just recently installed the 64bit version of WinxP Pro and could not find a driver for my printer. Just for the hell of it I installed the 64bit Vista driver and what do you know... It works perfectly. Other x64 Vista drivers work as well which leads to only one conclusion. Its the same operating system underneath with some eye candy added.
Same security bugs, too!
