For this price and the target market why are they not including TB3 and more ports? They are committed to keeping their users on their poorly designed dock connector when they are is a much better industry standard connector out there.
I love my SB1 although it's far from perfect. The dock connector does grow on you. Unlike USB-C, when someone trips over your cable the dock connector pulls free. The design of the SB1 means you can charge the tablet or keyboard independently with the same connector. And the $300 dock, while expensive, is better than any USB-C dock I've seen at providing a clutter-free desk with single attachment.
TB3 means that end user could attach their own egpu to a lower end (cheaper) model, and future proof it harder against potential SB4..
not to mention, that their proprietary connector only connects to their $300 dock!
I feel like everyone can learn from their competitors, but here Microsoft is emulating only the worst parts of Apple
