Ask Engadget: Best 4.3-inch GPS unit?

We know, it's a little late here on the east coast to be "thinking clearly," but we (and David) are pleading with you to pull it together in order to contribute. Afterwards, you and your freshened mind can shoot us a question to ask at engadget dawt com.

"I know, it's a really boring question, but the last time this was asked was 2 years ago. I'm looking for a 4.3-inch GPS unit with decent battery life (so I can walk around with it as well as use it in my car), Bluetooth for making wireless calls, and good voice-recognition. Traffic updates would be a plus, too. I don't care too much about multimedia functions. Is there anything out there that fits the bill? I hope to hear some advice from the community!"

As do we David, as do we. So, what's the verdict here, folks? Are connected units worth the monthly surcharge? Sound off below!
