For me the frustrations with NT 4.0 are all the reboots associated with changing settings, and the lack of plug 'n play (for USB devices). Those things aside it runs well.

Windows 2000 gets you a lot of quality-of-life improvements w/ a tremendous amount of bloat.

re: uptime - I've seen NT 4.0 machines w/ multi-year uptimes. I actually saw one running Microsoft Exchange w/ a >2 year uptime. I was shocked.
