I’ll admit I’m an Apple man, mainly because I’ve been working with them for my entire working career starting with OS7 I think, so the only system I know really. Would never say they are perfect, but I’ve never had what I would can major problems with their kit or systems. Admittedly Maverick was gash, but still worked. iOS8 and Yosemite have been awesome for me so far. On my Mac and home and work and iPhone 5 and 6 and my iPad.
Thing I find is all these new products whether Apple or Samsung or Sony or Microsoft (I’ll admit, I hate their products I’ve used) are all trying to ram so much new tricks and gadgets into them, probably find about 90% of them we never actually use.
