<h2>The YouTube-Friendly Touch Diamond</h2> <br> At 4 by 2 inches, the candy bar case on the HTC Touch Diamond is about as wide as the Apple iPhone 3G's screen. And at, The svelte (0.45 inch deep) Diamond isn't superthin, but it is slim enough to fit into your pocket. The 2.8-inch VGA touch-screen display provides crisp, bright images; and as with the iPhone 3G, you get an on-screen software keyboard for text input. The Touch Diamond's operating system is Windows Mobile 6.1--but you might not notice that at first glance because you can accomplish many tasks through HTC's customized TouchFLO 3D interface, which puts contacts, text messaging, e-mail, media (video and music), and Internet access at your fingertips. A built-in accelerometer automatically rotates the screen if you tilt the phone on its side. The device is primed for multimedia, too: It has a YouTube application for viewing any YouTube video over cellular or Wi-Fi; its music player handles MP3, AAC, and WMA format audio; and it comes with 4GB of internal memory.
