This can't possibly be $149. No way. The Line Dock is currently funding on Indiegogo (why don't they just make the damn thing and sell it instead of crowd-funding it?) and it advertises itself as not only a thin extended battery, but also a full USB-C dock with SD card reader, USB 3 ports, cooling fan, and Thunderbolt 2 ports as well. Once off Indiegogo, the Line Dock is supposedly going to sell for $249.
That seems like a ton of stuff for so cheap. I really want this project to succeed because it could potentially be a great MacBook accessory, but the skeptic in me says there's bound to be some huge hiccup in the future for this. And as crowd-funding projects go, I'd rather just sit it out and wait for the product to be on a store shelf. If it's good, it'll find its way there I'm sure.
PS: I also forgot that it's a STORAGE DEVICE as well. Seriously, no way they can pull this off at that price. Just no way.
