When GoPro launched its cube-shaped Hero4 Session camera, we wouldn't have blamed you for giving it a pass. Why pay $399/£329 (eventually $349) for an action cam whose main selling point is its size? There won't be any confusion from now on, though. GoPro has dropped the price of the Session to a far more palatable $199/£160 -- that's equivalent to the lower-end Hero+ model. You still aren't getting 4K video or an LCD, but those nice-to-have features may not matter nearly as much when you're saving this much cash.
