Adafruit is now selling the Arduino Micro in the US http://www.adafruit.com/products/1086

Comments on the Adafruit Google+ stream appear mixed - could it be other small Arduinos on the market? http://21stdigitalhome.blogspot.com/2012/11/micro-arduino-and-other-tiny-boards.html

Hi,
A direct comparison between

Micro: http://arduino.cc/en/Main/ArduinoBoardMicro
and
Nano: http://arduino.cc/en/Main/ArduinoBoardNano

makes me think that the only Micro advantage is the ability to act as a USB Human Input Device. If you want that, it makes sense. But well-done Nano compatibles cost a little less than the Micro.

The USB onboard the Micro (and the UNO) is both an advantage and a liability. I've seen several UNOs that have lost their USB firmware and the end users do not have the ability or know-how to reload the USB interface. I've only seen one FTDI chip go bad in over 3000 328 based boards.

Essentially the Micro is a physically small Leonardo and the Nano is a physically small Duemilanoave.

But I think it's good thinking and good design work, and if some really cool projects use it and make it's design choices work well, it's a winner.

The Micro is clearly a small, breadboardable Leonardo. But it is more expensive and while it does break out the SPI pins (both the data/clock lines only wired to the ISP on the Leo and the SS pin which is not broken out on the Leo at all), it is still slightly gimped compared to Adafruits non-Arduino 32U4 dev board, which also features the RXLED and HWB pins broken out. While one might be able to jumper some wires to the two NC pins, I do not think the Arduino label makes the extra price and effort for a full-featured 32U4 dev board worthwhile. Only good for those who cannot bootload it themselves, I guess.

Yes the price of the official boards (not one for one against a specific clone but in general against "like" boards) has been disappointing.  I would hope that buying the original is not like buying a Cadillac board as Makers are a pretty frugal bunch so prices should be guaged very close to market plus a dollar, maybe two max.

The difference on official shields vs. others is even more stark.  This is where Arduino could pump some serious innovation to leapfrog the available hardware and software but it really hasn't happened.  Lately more evolutionary than revolutionary,

Likewise, and with the USB onboard you lose about 2k of flash memory as well.

I've just finished the layout of a board that started with the mega32u4 (as used on the Leonardo), then I got to thinking about how reliable I've found FTDI chips to be in the past and how little I know about USB coding so I swapped to a mega1284 and an FT232.

Because I needed an IO expander with the 32u4 and don't with the 1284 the end result is the same in terms of PCB real estate and I get simpler IO, over 4x the program flash and 8x the RAM. Cost wise it will be about $1.50 more but that's worth it for the extra memory I think.
