I got my first PC (my A1600 netbook) so I could install Icaros Desktop on it. Aros is the only PC software that made me want a PC, a chance to use a newer Amiga OS on much faster hardware with modern enhancements was too good to pass up, and definitely the right price (direct from the distributor in China for under $200 delivered). Thankfully my netbook came with a blank hard drive and wasn't infected with the Windows virus when I got it.
I want a Mac too, a G4 Mac Mini so I can delete OSX and install MorphOS on it.
