Like many on this board, I'm waiting for some new OS4 hardware to appear.
In the meantime, I am tweaking my Amithlon machine. It's the closest thing to a modern Amiga I have.
Recently, I managed to get USB working on it.
Also, I have gotton RDesktop and TwinVNC clients working as well.
RDesktop is really cool. It's like having an updated BridgeBoard. I can open up my WindowsXP Pro machine remotely, either as a window on my Workbench screen or as a full-screen which I can toggle back and forth (left-Amiga-M). I can also cut and paste data between the two environments.
TwinVNC allows me to remote into a linux box. It's not as fast or responsive as RDesktop, but it works.
My next project is to get MIDI working on it. I'm not sure whether to go serial, USB or SB128 card.
I've gotton a couple real emulator programs working, E-UAE for running Amiga programs that need custom chip support (on Workbench 1.3) and ShapeShifter 3.11 with MacOS 7.5.5. Works really fast.
I turn on my classic Amigas every once in a while. They never fail to bring a smile to me.
