If you need an ARM development board for professional use I'd recommend a Beagleboard, Cubieboard, Odroid or any other board that doesn't have the aformentioned issues with the onboard audio, USB, ethernet, documentation etc. But then in my experience most of these alternatives are more expensive than a RPi. I like 'm but I can imagine people really having issues with them. I jumped the bandwagon not expecting much of it. So far the RPi exceeds my expectations for a $35 computing device. Jeremy

Yes, I've lost a card, maybe two, out of maybe 25 Pis running here and there. Not good. And fast cards (for hi res video) cost more than the Pi. > Bought my first RPi in the Fall of 2012 and that one, including all the > ones that came after it, have not eaten any SD card in my case.

The A+ is probably the most sensible model, the USB has worked for me for single audio devices, and for sensors ... it might even be better without that LAN chip, and for setup purposes a single USB-ethernet dongle for a whole collection of Pis will do it. Don't choose a Pi if USB is your interface ... they are much better for HDMI and GPIO uses. > The implementation is not that good but I can live with it.

Oh sure, there's a PDF documenting a few of the features of the I/O ports. There's no actual databook, like any good CPU core or SOC would have. > That's surely a major drawback. It is the biggest disappointment for me, especially given the sales pitch. Freescale and others do much better than Broadcom.

And a bit more $$ buys a hell of a lot more power and options. as far as professional use ... whatever that means ... the Compute Module is probably more the way to go, all the pins and none of the cheap peripherals, probably with much better docs via NDA etc with Broadcom. Raspberries seem best suited to setting up for a specific use than as a general purpose device, and the price might work out very well in that case. >>> Sorry, I like to stay positive but my experience with Raspberry's has not been good. > I like 'm but I can imagine people really having issues with them.
