well you pretty much answered your own question the moment "However ..." started.

I am not about to begin "hoping" for linux support ...
on top of hoping for driver support ..."which may or may not exist"..
on top of hoping and trying to count on a windows device that is still in the limbo of crowd - funding and may or may not perform as described...look as described ....or even make it to final production ...sales and shipping ...as described.

I have a tendency to wait until a long time after device release ....
now...
to see if everything actually measures up.
If it does...I am happily impressed ...curious about the device... and supportive..and willing to invest....time effort and money...in purchases...

Start-up crowd-funding is still quite new...as modern methods go...
I think it is great...and all..
many good things have come from it...
...
But I also see... that the old "soon" ...( mantra) ...
has quite quickly past "hope" and become an expectation..a given..

Personally I don't gamble on "possibles" any more.
Established devices with track record, good support and community are better than a gamble ..they are an investment.
