Didn't read the whole thread so if this was mentioned before I apologize. Samsungs greatest asset for me is the removable plastic back. Having replaceable batteries, and removable storage is a godsend if you travel like I do. Spending long hours flying international, and sometimes spending days on the road without reliable charging available. I have 3 batteries, at 100% when I leave and that will give me 3 days of GPSing, emailing etc.
When I had the iphone there where multiple times where I was sidetracked for hours waiting for my phone to charge.
Also being able to shoot with my DSLR, removing sd card, and instantly being able to edit, and upload shots allowed me to leave my laptop at home last trip.
The fastest way for samsung to lose me as a customer is to focus on fashion over function, and make their phones unibody without removable batteries.
Good on them for making such usefull plastic devices
This will save your life one day
