Is it possible to install it on VirtualBox or other virtualization solution? If yes, how fast it works?

            I don't see any problem running MonoTouch frameworks/IDEs in a virtualized Mac.
I can expect a lot of problems transferring across the USB cable the compiled applications to a real iPhone/iPad to test it. iTunes and XCode tend to be very picky about the configurations.
Buying a cheapest Mac might be easier and less costly if you consider the time you might waste, but your mileage may vary.

            The evaluation version of MonoTouch will run, but the SDK tools used on the production version wont.
