If you've had several different smartphones over the years, perhaps you've owned a slider (slide-out QWERTY keyboard) and a thin slate that only offers an on-screen keyboard. We're seeing fewer candybar designs like the Palm Treo or BlackBerry that includes a smaller screen combined with a small QWERTY keyboard on the bottom.
So, slider vs. slate? If you're a Verizon customer and you're thinking about getting an Android smartphone, that decision could boil down to:
Slider: Droid 2
Slate: Droid X or Droid Incredible
If you do a significant amount of typing on your device, then it's imperative that you test the keyboard on each of the devices and physically try them out. Before I picked up the Droid 2, I thought I'd be relatively happy with the QWERTY keyboard. After playing with it for 5 minutes, I realized that I'd probably end up using the on-screen keyboard over the physical QWERTY buttons. So, if that's going to be the case, then why should I get a slider?
The large on-screen buttons on the Droid X are easy to use because the screen is so large. The Droid X is larger (wider and taller) than the Droid 2, but it's actually lighter. 5.47 ounces for the Droid X vs. 5.96 ounces for the Droid 2.
