I love these sort of threads :-)
AmigaOne G3SE with 512Mb registered DIMM added, running at an adequate 600 MHz. Once OS4 comes this computer will be all I need for practically anything.. but for now I just play with Linux on it every now and again. have a tinker with the hardware.
Amiga 1200 with 170Mb hard drive installed with OS 3.1 hooked up to a trusty old 1084S monitor. use for old games and a few old apps i like to play with
Amiga 500 with 1Mb. In the loft but whenever I use it (hardly ever anymore) its for games which wont run on the 1200.
I would like more Amigas though!
