New mac mini should be the same size. But drop the 2.5 inch hard drives and make it come with a 256 PCIe SSD upgradeable to 512 or 1TB. Then, use the extra space for better cooling for an Iris Pro CPU. If people want more storage, get a freaking dropbox account or an external drive. End of story.
Also put the proper connections for display, whatever people want. 3 monitors for sure. Add newer Tbolt connector(s). Keep Ethernet for crying out loud. Firewire NO. I forget if it is on the current mini, but if it is, DROP it.
Also, would be nice not to make proprietary the PCIe interface so user could put in their SSD of choice. Sorry, spinners have been dead for a long time. Good riddance.
The design of the mini is darn near perfect. No need at all for a redesign. Those who want a round mini are certifiably insane. As are the square tower folks.
Next week I will really dig down and try to express how I REALLY feel
Me and my cat LOVE our mini!
