I own a KeyOne, released last year with Android instead of BB's own OS. I love it, only downside is that I had to import it as it isn't available in my country ... I'd mainly used Samsung flagship phones before and got really tired of all the bloatware as well as typing on a touchscreen. (Can't believe more people are questioning touchscreen typing on phones, I think it's horrible and I don't have the largest set of fingers in the world.) I bought it for roughly $500 and this is what I make of it after one year of using it:

The camera on my KeyOne is superior to anything I've tried before, I'd even go as far as saying that it's up there and competing with the giants. The Sony Z2 Compact camera is a potato in comparison. The keyboard feels a bit cheap and some keys make a squeeking noise, but it's still better than touchscreen typing by far. I've dropped the phone on a number of occassions, it hasn't broken once. The backside tend to pop out, but it's easy to put it back in place again. My biggest complain about the hardware would be the screen, as I haven't access to any protective accessories my screen is pretty scratched by now. It doesn't affect what's displayed on the screen (yet) however, but yeah, I think it scratch too easily. Like I said, the OS is Android, and it's been fairly problem free for being Android. However, lately it has been a bit too agressive in shutting down apps in the background. But I don't know if that is BB's own build's fault or Android in general. There are some pre-installed "security" apps which gives the feeling of the phone being more secure than your other average Android phone. I don't use them though.

My over all impression of the KeyOne is 8 out of 10 I'd say, and I think I'll keep it until it literally fall apart.
