All I'm going to say is I'm the only person in the office who uses Macs, we run 2 networks at the same time and 6 of us need to be connected to both, I'm the only one who never has network problems etc...
I've been using Mac's (and supporting them) for a number of years now, definitely less support needed than Windows, however a large part of that is down to the hardware/software support - much in the same way that iPhone apps, although not as many as Android apps, are more tested - the platform and OS is controlled tighter.
As for batteries, I've got 2 MacBook Airs, the latest and the original, my other half uses the original now (and then!) and the battery is still going strong even though it has to be 3-4 years old now...
