Until recently, Apple had no good inexpensive computer in its lineup. There was the Mac Mini but the graphics were crappy built-in on-board Intel adapters. As an ex Macbook owner, I knew how weak that chip is.
On the other hand, the Mac Mini with the 9400GF is a real computer. A Core2Duo processor at 2 GHz can handle anything except gaming and high end video editing.
I hope to hell my staff are not gaming and I know we aren't doing high end video editing these days. If we decide to start, I'll get a more powerful computer.
I know that when we do go to video editing, there are no audio and video sync issues on Macs (sync issues are the historic bugaboo of video editing on Windows computers).
We've just bought a total of six Mac Minis and Macbooks to switch Foliovision over to being primarily an Apple company. Here's why.
