Information Technology mentor Glenn Weadock responds:
You can think about Windows Millennium Edition, aka "Windows Me," as "Windows 98, Part 3." Due out in May or thereabouts, this home-oriented operating system uses the Windows 95/98 code base rather than the more reliable NT/2000 code base.

Based on a look at the prerelease software, I am underwhelmed. Millennium is such a small step forward from 95/98 that, in my opinion, it probably isn't worth the time it would take to upgrade. If you're going to upgrade your office operating system, I think Windows 2000 is a better bet. If you're buying new PCs for the office, my advice is to get them with Windows 2000 preloaded instead of Windows Me, even if it costs you a few more bucks.
