DesignWith its 4-inch scratch-resistant, shatter-proof glass display, the Xperia X10 is nicely balanced between the 3.5-inch iPhone 4 and the larger 4.3-inch Motorola Droid X and HTC Evo 4G. At 4.7 x 2.5 x 0.5 inches and 4.8 ounces, it's slightly shorter but thicker and heavier than the 4.5-ounce Captivate. The X10 is also the same weight as the iPhone 4. However, the iPhone 4 has a much more elegant glass and steel design.
On the plus side, the back is comprised of high-grade soft touch material similar to the Droid X, making it easy to grip. There are no buttons on the left of the phone, but to the right are nicely raised volume buttons and a dedicated camera shutter. On top is a power button and flap-covered mini USB port, with a 3.5mm headphone jack wedged between. For novice Android users, the Xperia X10's three physical buttons (Menu, Home, Back) may seem like standard fare, but the lack of a dedicated search button was a nuisance. We found ourselves reaching for the nonexistent search button often while e-mailing and web browsing, and realized just how much we've come to rely on it.
To make matters worse, the small white LED lights between the buttons barely help to distinguish them in dark conditions. And why use a square icon instead of a Home icon for home? Beneath the phone is the microphone, and on the back is an 8-MP camera accompanied by a light that Sony Ericsson wouldn't dare call an LED flash (we'll touch upon this later).
