For implementers, backpressure adds complexity without providing guarantees. The machinery to track queue sizes, compute desiredSize, and invoke pull() at the right times must all be implemented correctly. However, since these signals are advisory, all that work doesn't actually prevent the problems backpressure is supposed to solve.

Unlike the Flip, the Go lacks creative modes and more advanced features. Instead, it’s just a simple point-and-shoot camera, just like the Mini 12, which makes it a little easier to use. There’s no Bluetooth or companion app for added effects; however, the camera does include a self-timer and a larger selfie mirror. The smaller prints may disappoint those who prefer traditional Polaroid sizes, though, and its modern design lacks the retro charm of older models. But classic Polaroid cameras didn’t come with an app, either, and the Go’s simplicity makes it an a easy-to-use option that delivers a traditional instant film experience at less than half the price of the Flip.
