Highflyer, if you want to avoid both fanboi camps then you may wish to consider an alternative to both apple and microsoft. apple has a "walled garden" as far as hardware and software goes and microsoft are pushing their software to a "walled garden". They both want to lock you into their products and trap you there forever. Changing to the mac OS from windows will be a big jump but then going to MS OS X (windows 10 ) will be almost as big. Both companies are aggressively forcing people to the Cloud as is Google's Chromebook (something I would avoid like the Black Death)
Buy the hardware you think will suffice for the next 3 to 5 years and install a Linux variety. Will be a bit of a pain to get used to but it may be worth it in the long run.
FWIW, I service both apple and microsoft systems form Servers to laptops and dislike them both equally.
