Check out the first link for a general overview of MATLAB's capabilities in this area. You will be able to code MATLAB to drive motors, control I/O, etc., all without touching C if you do not want to.
You will need the support package in the second link, but with both of those, you should be set.<p>http://www.mathworks.com/hardware-support/arduino-matlab.html

The only thing I had to do was install the driver on my laptop (learn on this page: http://arduino.cc/en/Guide/Windows#toc4). I bought this board after repeated failure to get the 'ATmega328 w/ bootloader' (sku: DEV-09217) to work. I was using the 'Pocket AVR Programmer' (sku: PGM-09825) through USB on my laptop, but the laptop would never properly identify the programmer. I could upload the bootloader, but never upload any program. I've had no problems with the UNO board so far.<br>
I think I'm going to try and use the Arduino Uno as an ISP programmer next; see if I can properly upload a program to that AVR chip :)</p>

Fried 1 Arduino last year when 12V from a motor shield sipped into the logic channel of the Arduino. $4 for a replacement Atmega chip and I was back in action. Now I keep a supply of spare microcontrollers.<br>
Most of the time what fries is the CPU and replacing it is a lot cheaper than getting a new board.<br>
In addition, if you plan on miniaturizing projects, you can always pull Atmega right off the duemilenove/uno and embed it into the PCB. Not an easy thing to do with surface-mount chips.<br>
Get this for finalized designs (initially assembled and tested on Atmega boards with replaceable chips).</p>

The arduino comes with 'normal' female headers installed. What RobertC is talking about is the headers you put on the ethernet shield. The SparkFun 'Stackable Headers' have very long male pins, so what you see in that picture you posted is fully seated - the male pins are just longer than the female sockets<br>
But what you point out is still a risk. I usually place a square of electrical or kapton tape on top of the USB socket just in case.</p>

The long-term objective should be for the mega8u2 to drive debugWire on the main chip directly, but unlike ARM and TI, Atmel have not published their dW protocol spec so that unfortunately isn't possible today.<br>
I'm sure the Arduino team have already considered these ideas, but one can dream, right?</p>

http://code.google.com/p/optiboot/issues/detail?id=7<br>
I am wondering what version of the optiboot boot loader actually works and then see if I can somehow reprogram the bootloader on the SMD Uno's I have.</p>
Scanner on DEV-10356 - Arduino Uno SMDScannerurn:uuid:220bb0c6-1bfe-fc4d-fb3f-30fb2b066d5b2011-01-13T18:13:29-07:00<p>For what it is worth I see references on the arduino.cc forums to some people having problems with some versions of the optiboot boat loader causing "flash amnesia." That seems to be exactly what I am seeing with the two SMD variant UNO's I have.<br>
Being as these are UNO's I have no easy way to reflash the boot loader, at least not until I order some more parts. B-(</p>
Scanner on DEV-10356 - Arduino Uno SMDScannerurn:uuid:7cc1817c-7894-0c6d-9219-afa589926a6f2011-01-13T17:35:04-07:00<p>Hm. I just got some Arduino UNO's from sparkfun. Two as part of kits and just one by itself.<br>
Two of these (one in a kit, and the one by itself) are the SMD variant UNO.<br>
To be clear: The SparkFun starter's kit came with the non-SMD UNO. The inventor's kit came with an SMD version UNO, and I bought a third UNO that was also the SMD variant.<br>
Now, when I program the SMD variant one and the non-SMD variant one (via the Arduino app for OS X, on a mac obviously) the program runs fine.<br>
However, with the SMD ones, if I remove power and then power it up again, the program is gone, or not running. It just goes back to the boot loader blinking the LED on pin 13.<br>
However with the NON-SMD one, I program it, I remove power, I put power back.. and the program is running like it should be.<br>
Am I missing something totally obvious? Nothing anywhere seems to refer to this difference in behavior, yet both of the SMD ones are showing this and the non-SMD one is working as all the documentation seems to suggest?<br>
An Arduino that does not run its program after being reset or powered up is not very useful.</p>

And of course, they can provide or sell adapters to use existing shields. Let's just all remember that the Uno is entended to be for development. We are expected to DIY the final product rather than use a bunch of Uno's.<br>
IF Arduino wants to move into the current era, then they could redesign everything to be more like this... http://karuppuswamy.com/wordpress/wp-content/uploads/2010/10/ez430-f2013-450x281.jpg<br>
The MCU board is tiny and removable, just add 3V3. I use the ez430 on a breadboard as well. The MCU itself isn't direct competition to Arduino's for various reasons... but there is plenty of room on the other side of that miniMCU board to add a few more features. Suprising what you can fit into 2K of memory!<br>
Anyway... I definitely second/third the suggestions to remove the oversized USB & Power connectors and while we are at it, maybe fix those gaps in the headers... but maybe we should be telling Arduino and not sparkfun.</p>

(come on extra hot key buttons)</p>

Or if your mega328 dies, (which is the most likely problem with arduinos) then you can't replace it easily.<br>
Seems like this is a downgrade from the dip version, and should be at least cheaper than the original dip version.</p>

It would provide the shield vendors with an opportunity to sell an "adapter" board to take your original shield to the Version 2.0 standard also.</p>

I'm not sure how I feel about this... Every arduino update recently has made it harder and harder to DIYuino...</p>

Kids, don't put 12v where there should be 5v - it'll mess up more than your ATmega328. ;)</p>

Eagle files would be nice.</p>

Am I seeing this correctly? (I sure hope so.)</p>

I agree they need to redesign the board though. Those screw holes are too close to other stuff. Perhaps they could use a smaller USB socket, but it's not a big deal.</p>
