Expensive? Yes, but isn't it cool?
Yes, but only if you have a choice. The problem of OS4 is there is only überexpensive hardware, problem of MorphOS is there is only used rig (don't count he last Efikas though and am glad the Sam460 port is proceeding again).
The other thing is that I indeed have a faible for some exotic hardware, but an even stronger faible for a fast Amigaish System. In theory I would love an Amiga on Power(n) (with n most current). But in reality given the choice between an "Amiga" for 3000 US$ running an a semi fast processor that even is not fully supported or run an Amiga on a "boring" pc/Apple that just flies and dosn't drain my wallet completely dry I knew which one I'd chose...
