Well, I just ordered the last of the G4 MDD models. They are on clearance from the Apple Store. I was also able to get an educational college discount. I thought I would buy one before they are gone forever. I needed a Mac with PCI slots, so that was only the MDD or G5. And the G5 is way beyond my price range, so I went with the MDD G4. My current computer is a Power Computing Power Tower Pro upgraded with an 450 MHz G4 processor replacement. However, because the system bus runs at 50 MHz, and there are no AGP slots, it ran rather slow compared to what the MDD should be (I think). My current computer really was not that slow to me, in fact, it worked fine. However, it cannot run Mac OS 10.3, nor can it use AGP video cards, needed for many new programs. So.... any thoughts on what I should expect when I get my MDD? Do you think that it will be able to last me for quite a while? (I had my current computer for many years).
