>>Perhaps I did not even know there was more than just the "One" board at the time.
The Uno R3 is the latest based on the ATMega 328P.

The Leonardo is just a lower cost version based on the Atmel ATmega32u4.

The Arduino Unos and earlier models require "2 chips", thus being more
expensive.
1 chip is the main microcontroller that the user programs to run his app.
The other "chip" is used to emulate a USB-serial protocol, used for
downloading the executeable code
from the host computer.

Now- here comes the Leonardo. It is based on the ATmega32u4. So , it
is the microcontroller that is used
to run the embedded application, and as a bonus it contains a
USB-serial interface for downloading the code.
A 1-chip solution.

I haven't looked at the specs of the ATmega32u4 to see if it has the
same number of I/O lines as the 328, but
I would suspect they are very close.

There is also an Arduino ADK based on the Mega 2560, which is intended
to be used with Android
devleopment. It does have both a USB host & target interface. The
USB-serial interface is similar to what all other Arduino boards use
to download the executable code to flash.

The USB host interface is intended for connecting Android phones.

I have only used the Uno and two of its predecessors, I can't verify
the claims of the 2560 ADK.
