Hey Cappy !
Lots of power there !!! What are your plans for such a little beast?
Had you hit this thing with power yet and check it out ! Should be interesting to see how fast it can plow through "float" data computations. Wonder how it will compare to the PIC32 based ChipKit Arduino boards?

No immediate plans. I bought it for a future project at work, in case the
16MHZ Uno isn't fast enough. Better to have a solution on hand, before a problem arises, than vice-versa. I had the Dueomilenove sitting in my drawer for 4 years, before I needed to use it
The Uno only has 2 HW interrupt lines, my first project required that I OR in 6 signals into one of those lines. It worked ok, but was a lot of extra wiring. I didn't know about the PinChange interrupt library at that time.
The Due has more HW interrupt lines, well it has a lot more of everything
The PicChip version looks interesting. Everyone is jumping on the bandwagon.
I'm also interested in the Due, because I want to learn more about the Arm architecture. We use Arm for most products where I work.

Makes good sense and also subscribe to the way you do things. I have had some FPGA and Coolrunner CPLD development boards for over two years laying around and now I am finally developing some stuff on them. Its good to have stuff on hand.

I see, and it seems a great bargain for all that power !

Knowledge IS power my friend. The ARM is probably one of the most popular embedded processors now a days. I had studied the MIPS architecture for a while personally and have not done much with the ARM. The PIC32 is based on MIPS core architecture with a boat load of hardware modules glued to it. 
Have fun and I am sure we will see something grow out of the Due one day soon.

I plugged in my Due today, I'm quite disappointed that the IDE isn't very far along. One needs a special beta version of the IDE to work with the Due.
I was hoping to see how fast I could make the I/O lines toggle using digitalWrite() vs direct port I/O.
When I launched the IDE, it crashed- at least on 32-Bit XP SP3.
I may try W7 if I get time this week.

Wow, too bad. The Arduino IDE in all cases is very limited and stripped down and has virtualy no visibility into your codes operation. Definately not a comprehensive IDE like MPLAB for example but hell, it had to be written for visual artsists and folks new to MCU's to, not professinal programmers and hardware engineers ... lol. And its FREE !! yay !!

Seems a glaring error man. Intersted to see if the W7 will work for you The laptop I do all my programming on is W7 based so this is of special interest to me.
OK, awaiting your results
