This is an awesome question indeed, except that in my side is totally backwards. I was thinking of coding the AVR's in C, not in Arduino/Sanguino/Pinguino/xDuino, etc.

So, which one is better?

I was under the impression that the xduinos are basically good for people that are getting started and are afraid to delve into microcontroller territory. But if you are a programmer, you might as well do assembly or C, which will give you way much more flexibility as you have full access to the on chip peripherals.

Is my assessment correct, or has the duinos managed to brake that barrier?

BTW, all I know about the xDuinos is that there is a bunch of them out there. Other than that, I will plead 100% ignorance.

I am developing on the Atmega328 via Arduino. Can anyone explain what might be improved by transitioning to AVR Studio? More flexible, faster, more efficient code on chip, or is this more of a preference? I like the Wiring/Arduino language, but the IDE is lacking compared to Visual Studio, which I am used to.

That's good news!  Thanks for posting that.  Once upon a time, the order of installation was tricky.  Perhaps they have improved the 3rd party integration on both sides.  That makes things easier for everyone!

I use the STK-500 almost exclusively in development.  It's been replaced with the STK-600 but it still meets my immediate needs.  I've don't remember ever getting the JTAG to work properly, either.  I have the Dragon board and have done some debugging with the Atmel proprietary "debugWire" interface.  I find it best not to code any bugs in the first place.  :D  (OK, I stole that line from Mark Sims).

Dale - I built a new PC a couple of months ago, and installed AVR Studio *before* installing WinAVR (because I forgot), and AVR Studio seems to be working OK.  I can build an old project, at least, and recieve the standard GCC feedback.
What is everyone using for the hardware part of developing for/programming AVRs?  I've mainly used an STK500, but bought an Olimex JTAG ICE a while back, which I think may be defective.
I also have some ancient STK100s and maybe an STK300 kicking around.  It seems like the later versions of AVR Studio recognize different hardware than the early versions.
Come to think of it, I think the last time I programmed an AVR, it was with a serial adapter of some sort, which I had to talk to with a USB-to-serial adapter because that PC didn't have a serial port.
So, what's that latest/greatest?
