Seeing that the SAM3X has on-board Ethernet, but the Due doesn't have a port, I hope someone either builds a clone that does, or builds a simple (compared to current Ethernet shields) shield that adds the port.
This should really help lower the entry cost of using Ethernet in DIY devices, which I think is cool.

The Ethernet PHY is actually rather expensive, around $20. That's why the cheap dev boards don't have it.

#15You might also consider a STM32F4DISCOVERY board:

This is also a ARM Cortex board but it's $15 and in stock everywhere. (I think it's more powerful and has more features than the Due, but I haven't checked in detail. At $15, though, it can't be beat. And there are less powerful boards in the series that are even cheaper!)

#16€60 for shipping to US seems a little much for shipping 60 grams taking a week. Sadly none of the distributors seem to have it yet. Seems like we'll have to wait a little while longer still.
I'm sure SparkFun or some other American based company will import in bulk so you can get it cheaper from them.
Ture. I'll probably wait a few months and buy it from Amazon...

How does using an ARM CPU go with the fact that Arduino is open source hardware (while Cortex M3 isn't) ?
I'm not sure Atmel AVR microcontrollers (used in the rest of the Arduino line) are open source hardware either. Sure, they are fully documented from the user's perspective, but Atmel doesn't give away source (Verilog/VHDL/etc.) for the core.
(I'll give you that ARM is more patent-encumbered.)

That's true, of course. So, all I can hope for is that something like this (http://www.seeedstudio.com/depot/ethernet-shield-p-518.html?...) drops in price by $5 then (the price of their on-board Ethernet controller). :)

#19This is really exciting- the Arduino DUE is the board used in the Android ADK2012[1]. I can't wait to start building hardware to talk to my android devices.

I'll second the STM32 series of microcontrollers. We're using an STM32F100 chip for instrument control, and it was easy to include it on a custom PCB. It has many timers, and the performance per watt-dollar is amazing (as it is with any ARM chip). The STM32 series can be programmed with the gcc toolchain, or a number of commercial compilers (Keil, etc.). I've taken to using MikroE's compiler: http://www.mikroe.com/mikroc/arm/
Another alternative would be TI's Stellaris line. They have an inexpensive "launchpad" dev board: http://www.ti.com/ww/en/launchpad/stellaris_head.html?DCMP=s...
The downside to both of these is that they lack the ecosystem that makes Arduino magical.
Before the Due, the Maple board came out to provide an ARM board for the Arduino software: http://leaflabs.com/devices/maple/
As a side note, if anyone has experience working with the wireless version of the STM32 (the STM32W), I'd love to hear from you. I'm considering it for another product, but don't want to bother if there are serious problems or if the RF side doesn't work well.
