I agree with wanting an SD slot. Not everyone has cheap reliable unlimited data to use the cloud (yet).
Google have their reasons for not liking SD, thats fair enough. It would be different if they banned phones with SD slot from using Play services but they dont. The manufacturers are making that choice by themselves because, obviously thats what the average customer wants.
There is less and less choice of phones with expandable storage but i dont blame google for that.
I think we're gona see much bigger internal storage drives soon though
