The Droid RAZR by Motorola is 7.1mm thin, in fact, and holding it up next to the iPhone 4 makes Apple's phone look downright beefy by comparison. 

The RAZR's got a TI OMAP 4430 1.2GHz dual-core processor and 1GB RAM inside, and it does zip through apps with ease. The handset is rocking Android 2.3.5 Gingerbread -- or at least was during our hands-on. No word on Ice Cream Sandwich -- though we'll no doubt be hearing more about that OS at tonight's event. The 4.3 inch qHD Super AMOLED display is quite bright, and should do wonders on those Netflix HD videos.
