Jolla tablet VAT and taxes in EU, where will it be shipped from?

I think this might be only because of finnish laws on money collection. If you don't give anything in return (aka. donors who only donate to support) it is counted as collecting money (you need permissions for this) and not selling products (they would need to prevent any non-purchase donations). By taking the money through their Hong Kong office, they can get around this. Actual devices might still be sent from Finland, but you never know for sure before Jolla gives us more information.

Yup, sadly crowfunding is blocked by Finnish laws in many ways, some past cases here: http://www.arcticstartup.com/2012/10/23/legal-challenges-crowdfunding-finland

In Holland they add another 20 euro for postal services for collecting the VAT. (Legalised theft, I know.) I prefer to get it shipped from Finland, but I guess there is no choice here.

I would guess the reason for $ is that most if not all of this cash will go straight to Intel (their SoC provider), thereby making Indiegogo a more cost-effective option, since Jolla won't lose money through € > $ conversion fees when paying Intel (who will almost certainly mandate that they are paid in $), as they will be able to ask Indiegogo to pay the money to Intel, or pay it into their own $-based account.
