i use a macbook pro (2009 vintage) and a macbook air (2013). both have after market SSDs (MBP 500GB, MBA 1TB) and as much RAM as could be stuffed into them. Both machines dual boot OSX and Win10. The MBA has parallels desktop also installed.

I use the MBP for ARO, so I run Win10 an awful lot. The MBA is my general purpose and troubleshooting machine. The MBP is getting harder to find, which isn't surprising because it is user-repairable and ungradable, a feature that is rapidly disappearing from apple hardware.
