I would think that in some ways this is a superior power solution than using the onboard regulator, but the nagging question remains in my mind as to whether the traces to the leads on the board are okay with this method of providing power, and if there is any issues I hadn't otherwise considered?
I wished that there are cheap, rechargeable, common, high capacity 5V batteries so that I can bypass the regulator on the Arduino and save power!
Why does the processor run warmer when the supply voltage is increased? Does the regulator's output voltage increase as the regulator warms?
...and the AVR is quite warm compared to other voltages.

As for the FTDI chip, it's very simple to use and reliable, I like it. I just wish they had a smaller version, after all you only need about 6 pins.
