In my limited experience of Zen, the mouse mechanics are heavily flawed with a small window of usability, let alone viability. The software sucks, the mouse settings don’t do what they describe or don’t work at all.
Zen’s m/kb support is a hot mess and Zen is very far from being on par with a XIM, or a T2 for that matter, despite Charlie’s claims.
I'm also a Zen tester and I have to agree with the above 100%. Nothing seems to do as it says or is labelled and the skipping especially with swift movements is terrible. I don't understand the point of fanboys jumping to it's defence instead of pointing out these issues and trying to help improve the issues while it's still in beta, you'd think you'd want it to be the best it can.
It has potential but only if they listen and start to work out bugs and inconsistencies.
