Yep. I've been using my edge as the daily driver and whenever I use any of my androids as my daily driver I do miss things like all my messages syncing across my workspace and mobile devices. I always surprised how many of my contacts are actually iPhone users too, so whilst I can get away without iMessage for SMS, it's still noticeable to me. I know others like to chagrin Apple and its cloud services, but when they work - they work really well.
Most what I miss when using my androids is FaceTime call forwarding. Where for example in the gym I leave my iPhone in the car and just take in my iPod touch and earbuds with mic. The leisure centre has no mobile coverage once inside so best to leave obols in car. If I need to make a phone call, I can still initiate the call on my iPod touch to a regular landline or mobile and it's then routed through my iPhone wirelessly and without having to set anything up (just the iPod touch on wifi). It's a really neat ability and its that cross device harmony that is a really strong point for Apple.
With my androids as my daily driver, I can't obviously do that and I have to wait to come out of the leisure centre to see to my missed calls or to ring or respond / reply to text messages.
That being said I love the different androids too but do wish all of them would sync into my Mac hardware lifestyle as simply and efficiently ...
How do you set that FaceTime call forwarding up? Sounds great!!
