This one is IMHO best suited DE for cubox' meagre performance
(especially on I/O side due to microSD) as it incurs quite modest
I/O, CPU and RAM footprint quite suitable for PII-300 times
(cubox feels quite like that but has lots of RAM compared to
even maxed-out Pentium II workstation).

The image includes OpenSCADA as a nice and unique feature
which has been developed with TDE environment in mind
and was used on ARM hardware like N900, incidentally;
thanks aen@ for this suggestion.
