RE: Please fix the XPS 13 (2015) 9343 touchpad / trackpad
I sent a PM on Reddit to the Microsoft guy that did the precision touchpad AMA about the problems we are having. He replied with the following:
Dell's correct that there's nothing they can do for this - it's entirely on our end. While I'm not working on PTPs this release, I've forwarded your feedback to the current owners.
I agree that adding more features to the existing "built in driver" is Microsoft's responsibility, but I don't see that it would be difficult/impossible for Dell/Synaptics to port the existing Windows 7 drivers over to Win 8.1.
I wouldn't be surprised if it ended up being a frustrated developer hacking the existing Win 7 driver to work on Win 8.1/10.
The fact that Dell decided to go down the Microsoft driver route makes it their responsibility to sort out this mess. After all, we bought the laptop from Dell (well most of us anyways).
I for one will be holding off on upgrading to Win 10 until all this is sorted out (despite the shortfalls of the Win 7 experience).
