As a person who still doesn't understand what was disastrous about it (other than 3-5 guys complaining on TMO) or even bad, I certainly hope for many more similar disasters in 2015!

Jolla is cheaper, TOHKBD was a great success, Jolla Tablet as well, many people got their phones earlier for a discounted price, the coupon campaign generated a great buzz on social media...
If anything, it was a great PR success in my opinion. Even if there was nothing else, having mainstream tech media reporting about the possibility to buy the phone cheaper if you contribute to the tablet campaign is worth it PR wise.
Seriously, IMHO the coupon campaign was one of the best things that happened to Jolla in 2014, as it was pulled of perfectly. There were many mistakes before and after that, but seeing the whole coupon campaign, I was actually amazed by how well it was done. Then I saw this thread and was greatly amused.

Everyone it entitled to their opinion, though
