I doubt I would emulate an Amiga,...
I prefer the real thing too. WinUAE on my laptop doesn't have that much of an advantage in speed on my 68060@75MHz with Voodoo 4.
The old hardware is my main beef, floppys and mice just suck.
Get a PS2 mouse adapter and optical PC mouse. This makes a huge difference and works really well unless you have a pregnant mouse. Floppys do suck though. I don't really use them any more as most have errors. I do backups on multiple hard drives including my laptop I have networked to my Amiga.
Power supply, have an extra and I take the machine out to the garage and blow the crap out of it twice a year. I use it every day just because its reliable.
You have a pretty fast and reliable setup. I have a 3000T too. It's not my only computer and it can't do all my computing needs but it's still my funnest computer. The Amiga has a great community and still a few talented developers. I would expect the "classic" situation to improve as fpga Amigas come out. I hope you don't give up on the Amiga.
