Well, Cat S60 is the kind of phone that I really really really like. It can take a beating and has a few physical keys (I still miss the flip keyboard), waterproof and with thermal camera. Considering that my current favourite laptop is Panasonic CF-19, it matches what I need well.
It's just that the software development for the phone is abysmal at best. I can't blame Caterpillar since the company isn't really all about consumer electronics.
I know that phone well, a friend had one until he dropped something sharp onto it's glass. But it held surprisingly well, given that he constantly uses it on construction sites.
But without the bottle opener it just doesn't make sense for me personally
