Me too - been using Mac for 20 years but users are crying out for a proper touch based OS. iPad's environment is too enclosed. And that MacBook touch strip - WTF were you thinking Apple?!!!
I used to update my laptop regularly, but I haven't updated my MacBook Air for 5 years because Apple a) haven't released anything worthwhile updating to and b) it still runs current versions of Logic, Studio One and all Adobe programs without even a stutter!
Having said that I'd hesitate to move to a Windows machine, no matter how sexy Surface looks, I doubt very much it will still be running smoothly in a year, let alone 5.... Windows machines always slooooooooow dooooooooooown and become unusable.
Anyway back to Live...
