Yes, they should be. Then, you should uninstall the custom trackpad driver that does that, because that's not a built-in gesture. That was probably added by Synaptic, or the OEM of your laptop, and you should disable the gesture and probably let the OEM know that including that gesture was insane.
The rest of your complaints are, well, I think they're overstated, but I can't argue with how using the OS "feels" to someone. If you think it feels poorly done, me telling you your feelings are wrong is not going to get us anywhere. But at least factually, you should know that some of your assertions might be rooted in what OEMs have done to add crap to Windows 8.
