If you already have an iPhone, there are lovely little integration things that sound like small beans but are really valuable over time, eg.:
- copy-paste text between devices
- get verification codes from text messages to auto-fill in Safari on Mac
I don't know if Yoga 7 is good in this regard, but when you open the lid on a Macbook, it's awake and interactive before you've finished swinging it open. And battery life is outstanding. I'd miss things like that.
