The windows version of DOpus is great and well worth looking at. You can download a free 30 day trial of it to test what it offers. And you won't be disappointed. The way Vista navigation of directories works was being used in the Win version of DOpus years before Vista had it, and DOpus offers a lot of other advancements over the standard Windows Explorer that are well worth having. The search and batch file processing features are especially very good. I don't know what I would have done without the ability to use its batch renaming to rename large sets of files for web development projects.
And you are right about Win 2000. It was a great OS in its day and definitely one of the best developments from M$. I had it installed as my main OS very soon after its release and continued to use it as my main OS way after XP was released (only upgrading to XP once SP1 was out). Win 2000 was one of the best developments/jumps in OS design M$ have made to date, with many aspects of 2000 still obviously present in both XP and Vista. They are basically just updated versions of what 2000 started after all.
I still remember the first time we got hold of it on launch and tested it out on a spare PC at work to see what it was like, and being really blown away by how stable and good it was. Before this we had been wrestling with NT4 on our video edit stations, and Windows 98 on out workstations. Both a nightmare in different ways. It wasn't long before I had convinced my boss that I needed a faster PC and a copy of Win 2000 on it. At the time what I built was a state of the art Athlon 900MHz machine with a dual head Matrox G400 Max 32MB graphics card, 384MB ram, 60GB HDD and an Adaptec SCSI card with internal CD writer, external SCSI flatbed scanner, and when they came out, one of the first ever external Pioneer Authoring DVD Writers and a Pioneer DVD-RAM drive. At the time (2000/1) that was a great machine.
Times have moved on though. Windows 2000 is now starting to show its age. It is still fine to use as a business OS or as a server, but not if you want anything up to date. It doesn't support the lastest versions of IE, or DirectX, so you can be a bit stuck. Plus it is now out of date for design work as most Adobe and Discreet software has required at least XP as a minimum for a few years now, and some of the latest versions require Vista as a minimum.
Windows 2000 is still probably the most stable version of Windows to date. Although with SP2 or SP3 Windows XP seems to be just as stable, if not even more so. My test server and download servers both run XP SP3 and neither ever need to be rebooted (unless an update requires it) and both just keep on working. And saying that, my main PC running Vista 64bit is very stable too and nice to use.
As I have said many times. XP and Vista are very good OSs that run very smoothly and are both very stable if you are running them on powerful enough hardware. Windows 2000 wasn't nearly as resource hungy and used to run fine on a Pentium 2 400MHz machine with 512MB of ram, whereas XP really needs a 1.5GHz+ CPU and 1GB of ram to run as intended, and Vista really needs a 2GHz+ dual core CPU and 2GB+ of ram to run at its best. Although for Vista to run really well a quad core CPU and 4GB of ram is even better.
