Every Cat phone I've looked at was on the high end of pricing at the time it came out and on the older end of operating systems. I've been in the market for a serious rugged phone basically the whole time I've had cell phones and Cat has never been justifiable to me.
I lucked out and grabbed a Galaxy Xcover pro when they first came out. It's not really advertised for the consumer market, but it was also way cheaper than things I liked less that had been out for a year longer. I'm not sure if they'll come out with a new model anytime soon. I will say this thing has a removable battery, solid construction, and is plenty fast for me (though I'm not picky on speed). I'm still on the original battery and it will play music for 10 hours through my Bluetooth headphones and still have 30% battery by the time I get home. I really have no complaints.
EDIT: the Xcover does not have an IR camera. I got off on a tangent because I keep getting disappointed every time I look into Cat phones.
