Review: Motorola Backflip
The Backflip uses a capacitive screen. The screen itself does not have any performance issues. However, because Motoblur and the user interface itself can be sluggish, it would be easy to blame the display for poor performance. Rest assured, it's not the screen. It's the operating system.
Oh, and about that rear touch pad. Be careful. It's way too easy to send the cursor somewhere you don't want to, or jump forward or backward a page. It's sensitive .
