It would be interesting to see the stats..
Although Reg readers are more likely to be "power users", it would be interesting to see what the stats are for people buying Samsung phones and to see what percentage take advantage of the memory card slot and removable battery.
My GF had an S3 and then upgraded to the S5. She has never removed the battery, and never installed an SD card. If the vast majority of punters are the same, then maybe this is why Samsung have decided to dispense with these options.
I wonder also how many support calls Samsung have received due to someone putting a slow/poor quality/corrupted SD card in their phone and then having a go at Samsung because of it.
I have a Nexus 4, so am used to the no removable battery and no SD card. However, my Hudl 2 does have an SD card, but obviously no removable battery.
