I'm an Apple user since 2003. I still have my old Power Mac and the venerable PowerBook 12". They're retired now; stored in my garage!
Right now, I'm using a 2012 Mac Pro and a MacBook Air; I have a Mac mini on the living room and my daughter as an iMac. iPhone user also; since 2007. For me, the iPad an the Apple TV, are the the most useless piece of crap Apple as ever released. Only recently I've bought an iPad mini, for media consumption only!
I'm tired of reading posts of Apple fan wannabe people, just because they've bought an Air, iPhone; whatever. Apple is Magical and they need to trash everything non Apple related.
From my experience; Apple quality on hardware is getting worse everyday, since they moved production into China, QC is non existent. OS X is a mess getting bigger in bugs, in every release. Lion was a crap and Mavericks is plagued wit bugs. Windows 7 is good and Windows 8/8.1 is a good, solid OS. On every Mac I own, I've two partitions; Mountain Lion and Windows 7/Windows 8.1. They're both good tools to work and play. I enjoy both systems.
The Surface is getting better in every release. It's not an iPad competitor; face it; iPad don't have a real OS. The Surface as a work / play - notebook / tablet, is a good machine and right now, it as no competition.
If you don't like it, don't buy it! I have no brand allegiance; my next purchase will be this new Surface 3. A real innovation on a stagnated market.
