So i got the new Gopro Hero4, and it turns out to be a disappointment when comparing to the Hero3+. I compared between them (http://goprowoa.com), and found out that Black edition is just too expensive, and the silver edition is not as good as the Hero3+ black.
It's too bad they made it out of stock, I would rather buy it than the Hero4, especially that it came with the remote included.
the smaller new Gopro Hero could have been really great, but without wifi it is really going to be a hassle to operate. Maybe next year they'll upgrade it?
