The BlackBerry Curve 8300’s keyboard was so awesome I literally used it to take notes in meetings. (I had to tell people I wasn’t checking my email.) The integrated trackball made it easy to navigate the icon-driven interface — and play Brick Breakout — while the dedicated BlackBerry button made it a cinch to switch between open apps. Sure, the 2.5-inch display seems impish by today’s standards, but overall, the Curve was a killer productivity companion. Toward the end, I tricked out my back cover with Quagmire’s face. Giggity.
