I have no objection to removable battery. Yay!
1. removable battery with fully charged back up battery.
2. sealed battery and carry a power pack for travel.
both options are better than:
3. sealed battery, sit on the floor at terminal two near restroom because my phone is about to die and this is the only outlet available.
4. removable battery, forgot to charge backup battery, sit on the floor at terminal two near restroom because my phone is about to die and this is the only outlet available.
This is exactly how I feel. These people aren't travelers. They're amateurs.
