ME was basically 98 but much less stable, so a lot of people grabbed a copy of 2000 one way or another to run it at home. XP came out in 2001, bringing an end to DOS based kernels in the Microsoft lineup.

ME was the only consumer release in 2000.

2000 was the direct successor to NT4 and was specifically targeting the business market. It was available in Pro, Server, Adv Server, and Datacenter editions. I would not call it a consumer Windows OS.

Even cheaper when they were selling the Steam Link at discount, I think it was $30 for the link and controller? I dont remember. I bought one, barely used the link, just used the controller.
