they really did fug up the keyboard and trackpad. The 2 finger swipe to scroll like on macs barely works, you have to do it a few times to make it work. The keyboard, you can type well on it, but its not the most comfortable feeling and the space bar flat out sucks. I have to tap the SB pretty hard to have it register.
As I said elsewhere, scrolling with two fingers works perfectly for me, so it pretty much has to be a driver issue. In fact, I set the scrolling up to work in all directions, and it's sufficiently accurate and responsive to make scrolling sideways with the same gesture as normal scrolling completely practical.
totally is a driver issue
i use the linux driver and scrolling works like a charm
much better than on the previous Z on top of that. it works as well as the mac trackpad, except its smaller. but it really works very well otherwise.
