This is a great computer. The design is fantastic. Of course the MacOS is extremely easy to use. It's snappy at boot up and most any task I want to perform. I upgrade to 16 gb of RAM so that definitely helps. The only complaints I have is that it tends to run hot. Of course with the small form factor it's to be expected. I would recommend getting monitoring software to keep on eye on the heat. iStat is a great program for that. The other issue I have is more software related. When upgrading to the newest OS I started having issues with the bluetooth losing connectivity. The issue seemed to be resolved with a complete reinstall of the OS. A little bit of a pain, but it solved the issue. Ease of Use It's MacOS, 10.9.1 Mavericks in my case. MacOS in my opinion is extremely intuitive and easy to use. Anyone switching from Windows shouldn't have much of a problem, and Apple has some great resources for learning to use it. Hardware Quality In general the hardware is great. I did have a problem with my logic board going out. See my review for support & service. Support & Service Support is great with Applecare. When my logicboard went out they replaced it quickly at no cost to me. It comes with one year of applecare, but I definitely recommend buying the extended Applecare. Durability Again there are heat issues. Get the extended warranty. Design What can I say besides "It's an Apple." Performance Snappy components. The only thing I'm not super fond of is the limited upgrade-ability.
