This unit is only good for applications other than a phone. Great unit otherwise to use for all Windows apps. The phone is a bad add on, reception is poor, and if you can answer 3 of 10 calls you are doing well. The physical cursor control ensures you dial back your last call or caller a dozen times prior to them calling you and saying that they heard everything you said for the last 10 minutes. I have had 4 replaced under warranty for defective cursor controls alone. The battery life is less than a normal business day unless you have the expanded battery. However if you get a unit replaced under warranty, keep the battery in the unit they send you as a spare. If they call and ask about it tell them that the last one they sent was "end of life" and that the new unit you bought had a brand new one in it. They usually just say "ok" and that is the end of it.
Good PPC but really bad phone.
