I've said in the past (although not on here) that I won't give out that kind of info as I feel it's generally not helpful to people who have bought a less-popular one and can lead to MCIBTYC type comments). Each machine has it's own merits and I advise people as to whichever machine most fills their individual needs.
(Although, 'tangentially', I've sold more S/H RPCs and A7000s than new 7500-based machines, although that's not giving anything away!). Second hand Risc PCs - get them while you can!!!
