I have been looking at Mac for a few years now and I will certainly replace my 10 year old DIY desktop sooner rather than later. The only reason I am replacing it now with a new iMac is because supposedly newer iMacs will be released within the next 60 days or so (thanks to Intel's Skylake CPUs). That leads me to this question: Given that I am starting out on a Mac, which one should I purchase? There are only two I can think of that will not preclude me from buying an iMac in the near future: a MacBook Air (probably refurbished) or one of those retina MacBooks that came out in April. Any advice is appreciated.
