For computer sluts like me...

What they need to do is present why they're better for a particular application on a cost v. benefits basis.

I have Windows machines, Macs (PPC ones), Linux machines, an OS/2 machine, a BSD machine, and an Amiga. Each of them serves its purpose and runs the OS and applications suited to to that purpose.

It seems a waste of time to get single-machine buyers to prefer one machine at purchase just to bad-mouth it to other single-machine buyers later for its shortcomings. The big money, it would seem, would be in getting businesses and geek hobbyists who buy computers in lots to acknowledge that the right mix of systems includes many of yours.
