I wrote the chess program given away free with the early Apple IIs, made some good money on a Mac app in 1984, and until recently favored Mac laptops: a fan boy. That is changing. I bought an incredibly cheap and underpowered Windows 8.1 laptop in January (HP Stream 11) for $199 and like it quite a lot. I plan on getting either a Surface 3 or Surface 3 Pro soon, and will put my old MB Air on the shelf next to my Linux laptop to be used just as needed.
Microsoft seems to be heading in a good direction, Apple less so. Things like living in a web browser and a platform neutral IDE (I use IntelliJ for Clojure, Java, Python, PHP, and Ruby) make OS platform less impactful on using a computer. I am looking at Surface 3 Pros and Surface 3s, price and feature wise, vs. Apple products and I find Apple losing ground. The comparison is especially bad for Apple re: cloud services: Office 365 is such a good deal for $100/year compared to iCloud, with way more and better services.
As software engineers, money for hardware, software, and cloud services might not mean much, but I think it is good to look at what the general public will be using.
