32GB S6 only has 23GB of usable storage
A word of warning to anyone wanting to buy the 32GB version of the S6 the core OS uses 9GB which leaves you with only 23GB for personal use (see picture in review of 25% storage used). Now people would normally buy a SD card to get round these short comings but Samsung decided to ditch that useful feature along with the removable battery.
Rumour has it Samsung will release an Active version of the S6 in the summer with a removable battery and SD card slot and will be water resistant (another feature missing on the S6). Samsung already has S4 and S5 Active versions available in certain territories if you don't mind waiting.
Clearly Samsung want to appeal to the iPhone crowd. The S6 even features a glass back which even Apple ditched (yes there were a lot of broken back glass panels on iPhone 4/S a few years ago). Samsung have obviously calculated that they will loose some customers but hope to gain some of the trendy iPhone crowd. Time will tell.....
