Same problem here. The zoom function on both, touchpad and screen is pretty much useless. I'm browsing with firefox and zoom via touchpad is not working in a way you could actually use it. It only somehow works when you move your fingers very quickly. As a result, it is impossible to fine-zoom. I've tried it with corel draw on the tablet part only as well. Same issue. Zooming in only works if you move your fingers very quickly, hence, totally useless.
Just another issue on the long list now.
*tap to click not working with delay setting on
*camera frequently stops working after wake up
*zoom gestures with two fingers not working
*bluetooth access point frequently impossible to connect, only after restart reconnect possible
This whole thing is extremely buggy and unreliable considering it is supposedly a premium device. At least, I'm so thankful that the frequent system crashes are much better now. This happened several times a week after sleep/hibernate/wake up until recently. The updates made it much better. So I hope they can fix all the aforementioned issues some day. Needless to say, this is kind of disappointing.
