Couple of guys in my office did the same, but came back to OS X after weeks of suffering problems with high-DPI support, multiple screens, bluetooth etc.
Bluetooth is very broken too. Not sure if that's an issue with the drivers or the Linux bluetooth stack in general. Fortunately I only use it for my wireless headphones, which I can live without.
WiFi used to be a big problem when I tried Linux on a Mac at a previous job, thanks to terrible Broadcom drivers, but that all seems fine now.
Been running Linux on a Mac for 2 and a half months now, for me personally the improvements are significant and the issues minor.
