Having owned and operated PC's, Mac's, and LINUX, I'm now typing this from the best 'puter I've ever owned - iMac Retina 5K, 27", late 2014 vintage. Rock solid, *stable*, reliable, and the thing just plain works. Not looking to start the age-old PC vs Mac argument. Trust me, having been stuck using PC's & LINUX for many years while in my professional career, now retired, and having owned PC's in my home, there is not a single strand of any argument to dissuade me from the fact that Mac is the finest made. Oh, yeah, they're more expensive. Yup. And a McLaren Senna is more expensive than a new Challenger too. Glad you're happy with your Mac. We love ours.
