Of course we will if there is no other choice. However, if there is a choice between removable batteries and/or SD expansion then many will buy those because of those differences. I wonder if all those who make Samsung the top seller would still buy them instead of the more solid feeling Motos or HTC One if none had replaceable batteries and SD card expansion. I bet it's more than you think. Of course, no one really knows. Perhaps Samsung has done marketing studies that give them the answer, or maybe not.
I was in the store to get a Moto X until I realized that not only did it not have a removable battery it doesn't have expandable storage. I walked back out with my S3 still in my pocket. Waiting on the Note 3.
