I understood your point about the system users want, and Apple uses the iMac as the middle ground between a Mini and MP, which has no expansion. Others have issues with a built-in monitor (whatever the reason).yeah, you do have a point. but i think what i said still really applies here.
there are a lot of people around here who want a mac between the mini and pro for a long time. and it still hasn't happened. I'm starting to think that it won't happen
Apple sees the Quad core MP as the "headless" expandable mac users have been clamoring for, which is overpriced for what's offered, and why users have a problem seeing it as what they're asking for (generally speaking, as others may find technical faults with it as well).
