So is Windows Vista the next generation of Windows Me or not? No one really knows, except Microsoft. For those people who don't remember Windows Me, it's the operating system that Microsoft released between Windows 2000 and Windows XP. It was rubbish, I hated it just like everyone else. Sounds a lot like Vista doesn't it? I'll admit I've only toyed with Vista at this stage, but if you're looking to upgrade your hardware, stick with a Windows XP OS for now to wait and see how this pans out.
