No cancelling.
I am not in a hurry to swap my almost perfect 808 for a Jolla at this stage, so I can wait a couple of months.
2nd I purchased the 100 Euro to support not to demotivate Jolla later by cancelling orders well within reasonable terms of delivery.

I am sure I can receive the Jolla and resell easily to other people that like to have a hands-on try before they decide.
So I feel I will be helping Jolla be compensating for the lack of field presence and at the end -thanks to the setback distribution system by Jolla- it will cost me close to nothing compared to previous curiosity purchases of WebOS to name one.
