Re: No swappable battery, no sale
Not when you're camping in a field, trapsing half way up a mountain, sunning yourself on a beach or on a long flight it's not. ... Useless on a long train journey when my only entertainment is my phone.
Do you do any of those things at home? To repeat myself:
"a spare battery is useful for the times when you're away from a charger, which doesn't include when you're at home, right?"
We actually agree! :)
Then there's the fact that batteries lose their change over time.
That true, but it's beside the point. I'm not arguing that being able to swap batteries isn't useful, just that swapping batteries when one gets home is more hassle than simply charging the phone.
Those external battery/rechargers are so slow, it means leaving your phone off for at least an hour before things become useful again.
Not in my experience. Your phone will still work while being charged, and even so, do you use your phone continuously when you arrive home? Why?!?
The activities that draw more power than the charger is providing don't make sense at home; if it's sharing a 3G connection, why not use the WiFi? If it's watching videos or gaming, why not use the TV or PC?
Put the phone down and walk the dog, wash the dishes, talk to the kids etc.! ;)
