It did a few things right relative to Vista but it was also bad in many different ways, including but not limited to the (double) Control Panel

So it was a bit of a love/hate relationship.

Windows 2K is still the best ever made by Microsoft. I wish they'd just stay on that design and make incremental improvements to keep it fresh and modern.

I really liked Vista. It's problem aside, that were fixed in future Service Packs it felt like a new OS.
