Other than hardcore gaming where is it you need 64 bit?
Sdcard, agree but I'm willing to settle for 64gb version.
Battery: turbo charger tech, large battery, and my battery pack will suffice plus we are seeing more manufacturers go non removable (wired in) batteries. Helps with water and dust protection as the back covers have gaskets and I'm thinking they worried the consumer could either damage the gaskets removing the back cover or not install it correctly resulting in conflict over warranties.
