It was a solid device, but it got sluggish pretty quickly. Not sure if it was because of my mom's usage habits or the hardware.

And my first android phone was the Motorola cliq

I think I went through several devices on warranty because it malfunctioned in some way.

Anyway, I just mention this because smartphones with keyboards are not new inventions, but fewer are being manufactured. I don't think I would get a smartphone with a keyboard, but I'd love to see more innovation in this space. I'm kinda tired of the whole "more, better cameras" and "more processing power" pattern we've been seeing.
