Well as I see you are depressing.
First Atari clone is not Falcon clone.
Second Ataris (different models) arent so much compatible even to each other. You cant play most ST games on Falcon and use Falcon only programs on ST at all!
Milan has some drivers for PCI/ISA cards (s3 gfx card, ISA/PCI network card, TV card, several soundcards, ...
In future there will be Desse PCI DSP card for Hades and Milan.
As I own all Atari 16/32 computers and I own Milan I can tell you Milan is quite nice computer. If you find your Falcon slow you can upgrade it to 060 in near future. Just order ct60 accelerator.
Anyway situation is not depressing for me at all. Now I can even run Xwindows appliocations under GEM and even netscape (if I want usefull browser) remotely under GEM from other unix computer.
