-Very low power transmit/receive for the bluetooth (<4mA). I get around a week of battery life
-Cheap
-High speed on the SPI bus. The display writes are limited by the SPI bus. It requires a 9-bit word (additional bit is used for data/command). So being able to run the SPI bus at 48MHz is clutch.
-Has PMIC integrated into chipset. I don't need to include additional circuitry for a buck-boost regulator or a lipo charger since the dialog part has it all built in!
