I bought a Mac Mini (which sits proudly on my A2000
and it's been the most solid piece of hardware I've had in awhile. I don't know maybe Im easily impressed, but all the ports are USB 3, and the RAM is easily upgradeable to 16 GB just by turning the latch on the bottom. I think the 2014 version might even do 32 GB. And while I normally run Linux on it (nothing can beat its memory usage) OS X is pretty...and some of the features are actually innovative. Like if the recovery partition is gone, the mac can boot to the internet and download a copy of OS X...no license keys to keep track of. Works well if one accidentally...uh hypothetically....erases his hard drive.
