I saw some seriously souped up Amigas last year at a big trade fair/computer show at the National Exhibition Centre (Birmingham, England). 060, PPC, Voodoo 3, Soundblasters... the list went on and on. Some were A4000, some A1200, all in trendy towers with clear sides and flourecent lighting. Really cool stuff... but, and it's a BIG but... these things cost over 2500 UKP. Ouch!
I think I could get a G4 Mac AND a fast P4 PC for that price... and probably enough left for my favourite Sony Clie
