getting armed (was: Re: Raspberry pi )

[Marc Nostromo [M-.-n]]

My experiences with the beagleboard are extremely good. I'd say if you want
to try programming on embedded linux it's an extremely good choice. Not to
complicated to setup, quite a bit of horsepower and the ability to have a
direct display to trouble shoot the early days makes it a
very comfortable starting platform.

 For what it is I find it extremely cheap and, latency aside (I don't have
any test yet on how low it could go) I find it's perfectly suited for audio
tinkering.

Plus it nearly runs DFM1 :)
