I like my phone. It's a blackberry pearl 8100. It has a little trackball in the center (the 'pearl', I guess.) and a 5 x 3 key number pad with a qwerty layout, roughly 2 letters associated with each key. The combination of those two features makes it surprisingly easy for me to text on, but your mileage may vary.

I also get copies of my work email sent to it. It's nice.
