Samsung Moment. I remember choosing it for the physical keyboard.
I have a jelly 2 that I used daily for a couple of months and since then only touch it every now and then. For browsing the web and normal phone things it's pretty good. I actually like the thickness with how small it is. The battery life just barely got me through the day. It kills background tasks of apps by default but you can change that per app. Typing on it also works surprisingly well.
However there is bad. The fingerprint sensor is highly unreliable. The screen has really bad response times so there's a lot of ghosting. The speakers are also pretty bad. The camera is exactly what you'd expect as well. Also the update support is extremely limited.
I initially bought it to take with me on long runs so I don't have a bulky phone on me. Then I broke my primary phone so that's when I used it for awhile.
For the size and price though I have no regrets.
