The problem is really simple. Lots of people, myself included, need a computer with accessible drives to be replaced, and it would be really nice to have a PCI bus. Apple offers this, but only at an outrageous cost that includes 6, 8 or 12 processors, which we don't need, and also the PCI-e bus has extremely few normal cards available, because Apple sells so few Pros, because they are massively overpriced. The alternatives are iMac, MacBook and MacMini, none of which have the current industry standard USB3 ports, all of which instead have a weird nonstandard Thunderbolt connector that requires $50 intelligent cables and for which no virtually no peripherals are available now, or ever will be available, except at extravagant cost. It's a serious problem that affects my work, and the work of many, all due to mismanagement of their computer line by Apple. I have around 4TB of files I regularly access, including video archives of tutorial and marketing films. On a Mac Pro, I can drop 2x2TB drives in and be ready to go, and even have a couple more for mirroring, but the price of the chassis to hold the drives (the Pro) is outlandish. With the iMac, you can't upgrade to that capacity at all, and even upgrading the internal drive to 2TB is trouble because Apple puts custom chips on their drives that prevent the temperature sensor from reporting right so that for many people upgrading the drive makes the fans run at full speed. Putting the drives into Firewire enclosures means I have to buy rare and expensive FW800 external housings, daisy chain them, and have multiple wall warts, transformers, enclosures and wires all over the place, just like back in the Commodore 64 days, and if something gets snagged on one of these cables mid drive write, the whole system becomes hosed. For a platform historically known for suitability for multimedia work which has always required fair amounts of storage, the situation is abominable.
