Ask Slashdot: Best Dedicated Low Power Embedded Dev System Choice?

An anonymous reader writes "I'm a Solaris user which is not well supported by the OSS toolchains. I'd like to have a dedicated Linux based dev system which has good support for ARM, MSP430 and other MCU lines and draws very little (5-10 watts max) power. The Beaglebone Black has been suggested. Is there a better choice? This would only be used for software development and testing for embedded systems."
