It's been difficult using AmiagOS primarily for fifteen years, before using WindowsXP and finally going back to AmigaOS again now that WinUAE is working satisfactorily.
There are things about XP I like, the task manager being one as killing an unstable program without having to reboot your system is a luxury. Multi-user support too is welcome, as is the way that XP treats media files and pictures (ie showing them as thumbnails in directorys).
And then I think of all the things that frustrate, like slow boot times, the spyware issues and MS's obsessive need to be the biggest name, if not necessarily the best quality...
If you flip between my PC and Amiga desktops, you notice similarities, but that's because I like to tweak my desktop a certain way, with certain colours.
I love the way that Amiga's OS is so damn configurable, the way that Visual Prefs and Birdie seem to produce stunning results with little or no CPU overhead (which let's face it is critical on the vast majority of our systems). I have spent hours tweaking the GUI to a fine degree and am mostly pleased with the results.
If only I could remember how to get Birdie to work!
The problem with the above is that it isn't integrated into the Amiga's actual OS. It would be nice if it were, as we'd all have destop eye candy to rival anything else out there, but the downside is that fiddling is required to get Birdie to work, to make sure the palette in Visual Prefs is locked etc. So many times I've got the colours spot on, only to save my preferences and be greeted with Magenta window borders.
