I'm all for open source/libre software. A free download != free software :)

Free, but not open source again..

The main reasons for going for the atom board are

- Super easy packaging - I won't need to solder anything which i'm notoriously 
bad at..

- Ability to use open source software exclusively (Linux, Ingen, LADSPA, DSSI, 
LV2, SuperCollider) which i'm quite familiar with, which will save me loads of 
time..

- It has an FPU [which you do not get on any DSP in the 70-Euro price range 
(including board)..

- Cost: Total price will be around 250 euros, including the case, switches, 
the Arduino IO, etc..
