Is it still worth it to buy the KNC Jupiter?

[Nemo1024]

At this point my answer would be if your delivery date is likely to be Sep or Oct, then yes it is a pretty good bet.
If not, save up and wait for genertion 2 which will be beginning of next year.

...by which time you'd need to ask the question whether it is still worth buying gen2 or not

That EU law (distant selling) is when dealing with consumers. Private buyers only, not bussiness.
KnC 'Terms and Conditions' states, they are selling to bussiness only, and then there is no consumer protection, and no 'cooling off' period.

Bullshit, you have absolutely no idea what you are talking about. You've been reading into posts by KS and he is a troll who has lost a lot of money on Bitsyncom purchases (in excess of $100k), and spends an inordinate amount of time spreading FUD in the KnC thread with no intention of purchasing, yet goes and dumps $100k+ (that was only on the boards and assembly, let alone chips) with an unsecured payment method. Do some fricking research and stop spreading crap.

Unless specifically underwritten in the terms and conditions, as an exclusion clause your statutory rights, in the Uk are upheld. Presumably this is EU wide, but double check in which weever country you are from.

How do you know if the contract (business to business) takes away your statutory rights?

If the person who sold you the goods or services has taken away your statutory rights, there should be something in your contract about this. For example, it might say  the seller isn't responsible for goods that are unsatisfactory, don't match their description or aren't fit for purpose. Or it might say that the seller isn't responsible for any loss you've suffered because of their lack of care or skill. This type of content in a contract is called an exclusion clause.
