Pure craziness...
This is going to sound crazy to some (except the ppl who merchandise Apple stores), but the really great thing about the Mini is that you can make a really space-efficient workstation by combining a large-screen LCD with a tiny computer to maximize your space. The previously unimaginable form-factor in combination with Tiger and a high-end monitor makes computing truly enjoyable.
Sure, the Mini doesn't support Core Image, and the graphics processor is not exactly stellar, but if you simply value the Mac experience and, like most people, mainly surf the internet and use basic entertainment and productivity apps, then the small computer, large screen theory works well. It's not really a solution tailored to a low-budget Windows switcher, but it actually makes sense for the vast majority of home and business users. (At full retail, my setup would have cost around $2200 before tax, peripherals, and network hardware. Pricey, but it does what most people actually need.)
Of course, we'll see what my Visa buys me when the faster Intel Macs come out...
