There's A SIM Slot
In case you missed it from the previous slide, HP slipped a Micro-SIM capability slot into the Revolve 810's MicroSD card slot, allowing it to operate on HSPA mobile broadband networks. There's also dual-channel Wi-Fi, Bluetooth and NFC. Since the Revolve can transform into a tablet, it needs to do tablet-y things. So it's got a built-in gyroscope, accelerometer, compass, ambient light sensor and SAR proximity sensor. In tablet mode, controls are accessible for volume and power, and there's a dedicated switch for toggling screen rotation.
