The Nexus One has about everything: quad-band GSM, tri-band UMTS, 802.11b/g/n, A-GPS, 3.7″ AMOLED screen, 5MP auto-focus camera with LED flash, and a really powerful processor. It’s 512MB of RAM is respectable, but non-volatile storage will depend on a micro-SD card (4GB bundled) because the 512MB of flash is too little. Perhaps the 512MB flash is really just for the OS and apps. It also has a digital compass, accelerometer, and bluetooth 2.1+EDR, all features one would expect in modern smartphones.
