Personally, no.
My threshold to spend money on crowdfundings sank drastically since i work selfemployed, live out of the suitcase in hotels all over europe and have not much time and need to spend money on common material stuff.

So crowdfunding is an ideal fit for me.
I have news on a topic that really interests me and if it succeds i can enjoy the device much more, having a history with it.

And that exactly is what i am doing already right now, sitting in a cheap hotel in Rostock, accompanied by pretty awesome mr. "2007 Müller-Ruprecht Spätburgunder", checking for your all thoughts about that turing thingy on functional kaputt hotel wifi and call it a relaxing distraction

cheers!
