All these new Apple things and I'm still thinking about jumping off the Apple ship. (not getting rid of my iMac though)
But mobile stuff ! I might give Windows a go. Its the getting stuff on and off thats a royal pain for me (iTunes)
As for the watch. Mmmm ? NO.
I have a nice analog one that tells me the time only.
i liked that the windows tablets could run lightroom... but in 2015 theyre will be the new photos app that runs cross platform for all the apple stuff with reasonable cloud storage, so ill go that route
