I Loved the HTC One, But the Romance is Over

[Christopher1]

I stopped using HTC when they dropped removable batteries and micro sd card slots.

Well, remember to read why they are doing that: supposedly it allows them to make devices a sliver smaller than they would be with those features.
That said, I too will only buy a device that has a removable battery unless it is able to go for at least 6 hours while talking on it on a charge.
