Where can I order? None of the distributors mentioned in ST site have this in stock.

  Digikey has some in stock, but at $19.50. http://search.digikey.com/us/en/products/STM32F4DISCOVERY/497-11455-ND/2711743 http://search.digikey.com/us/en/products/STM32F4DISCOVERY/49...

That is a pretty great deal. Mouser has the chip alone in qty 1 at $17 http://www.mouser.com/search/refine.aspx?N=4294966131&Keyword=STM32F407VGT6 http://www.mouser.com/search/refine.aspx?N=4294966131&Ke...

168 MHz, since I couldn't find that in the article. The price/performance seems poor compared to 65-cent M3s, but the performance looks impressive.

  This is $15 for an entire board, but it will probably take a bit of time to get volume pricing lower. For $15 it seems like a good deal for a development board and chip.

Do uboot and/or Linux run on this board?

  It has 192 KB of RAM.

    But no MMU

They recently sent one of these to me for free [1] as part of a promotion for robotics enthusiasts. It runs DFU for its boot process, they have examples for various compile system IAR/Keil etc but no explicit gcc support. Looks similar to the NetDuino space although frankly I'd love to see a microSD card slot for holding stuff rather than simply relying on the on-chip flash. I'd love to understand the lowest cost HDMI compatible frame buffer interface one could put on these. I've got an idea/application that I started prototyping on a Chumby which would benefit from their price point.

  With an ARM11, HDMI and SD card, would a Raspberry Pi suit your needs? http://www.raspberrypi.org/ http://www.raspberrypi.org/ ETA December at current rate and enough real world examples at the alpha stage to be a cut above vapour :)

  I got in on that promotion also. I joined the IRC channel but have been too busy to start doing anything with it. Pretty interesting. Especially with the motion/sound sensing and audio out built in.
