The key to the P31F is small size, huge battery life and integrated 3G allowing business users to access the internet anywhere without an external modem or tethered phone. The P31F has an integrated slot for a 3G HSDPA enabled sim card hidden underneath the battery. The rest of the specifications are good with the performance of a core i5 processor and the Windows 7 Professional allowing business users to connect into corporate environments and VPNs. This unit ships standard with a 2 year warranty, showing that the brand stands behind its products quality.
