So, I`ve been using a HTC One for a while and there`s something confusing me, the device has a sim tray that pops out with the use of a small tool and one of the reasons that they didin`t add a microsd card slot was because of the so called unibody closed design, my question is; if they were able to put a sim card tray, wouldn`t putting a microsd card slot with the same tool thing removal be just as easy ?
