Being that I am a PC guy, I really like this small, out of the way, design. In fact, it might be my first MAC purchase ever.
However, here are the issues I have with it.
1. Power button looks like the only power button is on the back I/O panel, so every time I want to turn it on, I have to fumble through the wires on the I/O panel to turn it on. From what I could tell, I could not see any power button anywhere else, from what they showed us. Now, that doesn't mean it doesn't exist, just didn't see it, yet.
2. The Headphone and Mic Jack is on the back I/O panel, again forcing me to turn it access it.
3. No front USB ports, again forcing me to turn it to plug in.
4. Memory Card Readers, no sign of this either. Can you see a pattern here?
5. No expansion. But since I have never owned a MAC before, not sure I will need to expand outside what it already has.
6. Optical drive...no sign of it. Again, doesn't mean it is not there, just didn't see it. I know, plug it into either the USB or Thunderbolt
Now, with the 6 Thunderbolt 2.0, 4 USB 3.0 and 2 Ethernet, you can have a bunch of items connected to it and keep your desk just as cluttered as before.
But like I said, I love the design, just how functional will it be for those who have Mac Pros already???
