Small curiosity: Is Arduino used purely by hobbyists, or is it being used in the industry anywhere?

It depends what you mean by industry.

No reasonably qualified electronic engineer would use the Arduino platform in a commercial design. Most managers would laugh at any EE who suggested such a thing. I am not aware of any mass produced (consumer, not hobbyist) product or device which uses the Arduino platform. In the industry of fashion and art (which I know very little about) many makers/creators/designers are incorporating Arduinos into art installations and fashion items, although from what I understand these are mostly one-off items.

Arduino's are definitely used at the proof-of-concept stage but will never make it in to production simply because they're too expensive for that.

Why not use the Arduino for rapid prototyping then the once you figure the design out, lay out a board based on the Atmega chip? (or some of the lighter-weight chips that would run the same code...)?

It sounds like 8 years ago when "most managers" and "reasonably qualified" programmers would get laughed at for suggesting ruby or python for a serious production project.

The reason it doesn't get used for serious or complex projects is simply because of it's lack of capabilities. The big one is debugging and this is a huge reason for why you won't see EEs using these at their day jobs. Electronic engineers are accustomed to being able to step through code, watch variables and all the other niceties that in-circuit debugging offers. With Arduino you lose all of this, your flying blind with maybe a flashing LED or a serial output to help you out. Who knows how you will detect elusive bugs like out-of-bound array errors. The time you gain with some nice wrapper functions and libraries you will quickly lose when trying to debug a complex project. Features wise, you can do things most of the more advanced features which require bit manipulation of the AVRs registers like interrupts, timers, etc. with Arduino. Though at that point the lines are so blurred because half your code is AVR-GCC and half is Arduino. Why don't we see the simple consumer products using Arduinos? I don't know for sure but it's most likely because something simple is just as quick to code without the Arduino libraries.

Atmel and most other micro suppliers are now coming out with their own "frameworks" these days, which are similar to Arduino in providing libraries for common tasks with a similar level of abstraction to Arduino, without the loss of the higher level functionality like debugging. These are a lot more attractive to EEs than Arduino is.

It will be interesting to see how this changes over the next 5 or so years. By then most of the young engineers who grew up with Arduino or were even introduced to electronics with Arduino will have graduated University and will be working in the industry. It will be interesting to see the effects that this generation of new engineers have.

What are the interesting frameworks these days?

The closest ones I know of are FreeScale's PE (Processor Expert) which has been around a while and is quite decent; I've used it with the HCS08's.

TI started one for its MSP430's called Grace this summer, but it's very very primitive thus far.

Atmel also has one called FLIP for its USB-enabled MCU's to make them act as various USB profiles/devices.

ST has a very nice "Standard Peripheries Library" for their STM32 ARM Cortex M3 line which abstracts all the bit and register manipulation away in a very elegant manner. Atmel has the "AVR Software Framework" which I have heard good things about but haven't used it myself.

Nearly all the chip manufacturers I know of have some sort of framework/library for their Cortex M3 line (which is what is in the new Arduino).

This is simply not true. I work with quite a few of these reasonably qualified electronic engineers, EE's and managers who all love how fast we can turn out prototypes and concepts using the Arduino platform. True that the platform itself does not go into commercial designs, but the ATMega168 and 328 chips certainly do and priced quite competitively at quantity.

Mostly hobbyists, but there are a few exceptions. For example, the Makerbot Thingomatic 3D printer uses an Arduino Mega as its mainboard. Makerbot had more than $1M in revenue in 2010.

I suspect that Makerbot sticks with the Arduino Mega because it makes their hardware hackable by their users, which is worth more to them than the reduction in parts cost (minus the non-recurring increase in engineering expense).
