In so many respects, being small or smaller isn't considered a great thing in our society. We live in a time of upsizing, plastic surgery and SUVs. Bigger is better, biggest reigns supreme. And then you have the Razr M, a perfect example of where smaller means a better fit and better performance.
On paper, the size difference between the Razr M and the Razr HD may seem insignificant, but in the hand, the HD does feel much larger. It is both taller and wider, which is obviously necessary to accommodate its larger screen. The Razr M makes better use of the size available, with a thinner vertical bezel, which Motorola is calling it's "edge-to-edge" display.
