One important note: the SSD option is available in addition to the regular hard drive. If you choose both, the SSD will come pre-loaded with the OS and applications, and the other drive will be free for storage.
This is terrific, and a very welcomed option for many people. The speed and power of SSD is ideal for booting your OS, but you won’t have to struggle with the smaller size of the drive and rely on external storage.
If I end up with one of these, I will probably not order one with a built-in SSD (at a cost of $600), but add one at a later date.
This certainly shifts my interest away from a Mac Pro. I have one now, but really don’t need the 4 drive bays anymore. Two is just fine.
