The 10-ounce Sony PRS-700 may lack a keyboard, but it boasts a touchscreen--which explains the setup of the main Home navigation menu. Big, roomy buttons dominate the screen, one each for Continue Reading, Books, Collections, and All Notes; three more buttons, Audio, Pictures, and Settings, line the bottom of the screen. I appreciated the PRS-700's display, but I disliked having to press hard to make the touchscreen work. I could use my finger to select words and annotations (not easy with the on-screen touch keyboard). The screen supports gesture motions, too: Conveniently, I could swipe my finger left or right to change pages (even at an angle--neat), and swipe and hold my finger to jump through multiple pages at a time. But even with page swipes, I thought the pressure required to accomplish tasks was unnecessarily hard, and nothing like what I'm used to on, say, a Palm Treo 680 or an Apple iPhone.
