Well the keyboard is in the stand, part of the battery is probably in the stand, all of the ports are in the stand, the dedicated GPU is in the stand, plus the stand actually lays flat while the screen is mostly upright so in any normal position the stand could only be a fraction of the screen and still not cause it to topple right? I guess the combination of all of that and perhaps a little extra counterweight if necessary makes it work out okay.
A quick comparison, Microsoft cites 1.6 pounds as the weight. I'm assuming it's the screen only as the Surface 4 Pro (the tablet computer) alone is 1.73 pounds, and the Macbook Pro is 3.48 pounds. If the stand held the GPU, a battery pack, keyboard (and possible counterweights) and weighed as much as the screen, it'd be 3.2 pounds and still a fair bit lighter than the MBP.
None of the Surface Pro range has ever been either flimsy or plasticky. At the launch, Sinofsky put wheels on a Surface Pro and used it as a skateboard....
Yes, I've used all the Surface Pro keyboards. However, the keyboard is an optional accessory. You can use just about any USB or Bluetooth keyboard you like. You can probably get something industrial strength, if that's what you need....
However, I suspect we're talking at cross-purposes here. I don't know about the Surface Book keyboard. I watched the webcast but have not had a hands-on....
