I haven't used a keyboard-equipped phone in years, but the Q10 makes it very tempting. There's no getting around it: it's a faster, more accurate way to type, even compared with innovations such as Swype, which lets you "type" by swiping your finger from letter to letter.
The keyboard eats up space that could be devoted to a bigger screen, of course. But BlackBerry has saved some space by eliminating the big buttons that resided between the screen and the keyboard on older BlackBerrys. This results in a larger, square screen. It's very sharp and colorful, too. To some extent, the 3.1-inch screen compensates for its small size with a high resolution, which allows it to present a lot of information, as long as you're willing to hold it close and read small type.
