I hate to say this but winuae IS the ultimate amiga.
It may not be a "real" Amiga, but what is a real Amiga anyway.
It's faster than any amiga out there, it has everything you need to connect anything you might imagine and of course it doesn't "Guru" so often. At least not that often as my old 060 1200.
The beauty of WinUAE is that you can have ANY configuration, in ANY hardware setup in just seconds. In my real 030 Amiga I use WHDLOAD. In UAE I use just... as many configs as I like for each game. I just click the game I want. It loads ultra fast in "turbo mode" floppies and I can also record in .avi all the action. As for Workbench use, it is in fact easier to set up any workbench in UAE than in real amiga. I have many (so many) different Wb's set up in my UAE that I can always have a "clean" machine to work with. I have made different setup of 3.9 with scala and dpaint (for gfx), a different setup of 3.9 for games, another one for music etc. It is a matter of seconds to load the appropriate one, and it takes so little space on a 1TB HD :-D
