A month or so ago, I reached out to them using their customer support form asking for advice on a graphics card upgrade. I got a response within 24 hours that was clear and helpful. If they ever offer desktop (or even laptop) worthy ARM based systems, I shall aim to be amongst the first in line.
I do recommend maxing it out, i got a cheaper spec and it can be sluggish for multiple heavy loads, like three browsers at once (cpu bound).
