While better than Windows 9X, Windows 2000 was also horrendous with regard to security. That was the era where Windows saw so many exploits and worms, and their security practices so lax that because they started the firewall a few seconds after starting the network interfaces when booting, if you were connected to the internet without a separate firewall on boot (fairly common at that time) it was likely you would be infected by a worm in that few seconds of unprotected networking.
Anyone around at that time will remember the rampant worms infecting large swaths of the internet connected Windows machines. Code Red. Sasser. Blaster. Slammer/Sapphire.
Google Docs (and the subsequent migration of MS Office to web accessible forms) didn't come until even later.
Microsoft's web apps are a grim reminder of how desktop UIs have evolved backwards. (I’m in the midst of evaluating Office 365 as part of some IT transitions at work.) It's missing tons of features even compared to Word 2000. And it's a total pig. I thought Office was a pig before, but moving it to the Web made everything 10x worse. (Google Docs is less of a pig, but that seems to be because it has less functionality than Gobe Productive on BeOS.)
I’ll concede that Google Maps is better than what was available in 2010. It bet it would be even better if Google turned it into a Win32 desktop app.
Sure, that's all true, but this backwards devolution also ensures the important thing: that you don't really own the code you run, a centralized provider does, and they can change or break it as they please, without having to remain compatible with your machine. This is a business model problem: they've decided they do better off turning your general-purpose, user-programmable personal computer into a dumb terminal that uses 10x bloated-ass Javascript frameworks to make AJAX calls to their HTTP servers.
I'd love to go back to the irreverent hacker spirit of the 90ies.
