OMG, I think it looks awesome
As someone who actually uses Quark as my primary tool in producing a physical magazine, I must say this is really great.
I prefer the simple power-user friendly interface that Quark has, with great keyboard control, and a consistent GUI that hasn't changed much for a long time. Rapid development is really useful for power users and nerds, but I could never get our editors or business staff to learn a new program like InDesign without much cajoling.
That said, I am anxious to get a better and carbonized version of Quark on my machine. I have a strong need to transition to an XML workflow. I must have multiple undos ASAP, and I really want some better batch processing functions soon (better scriptability at least).
Unfortunately for Quark, even though I'm sure our editors will throw a fit and I'll probably have to ban them from page production, I am quickly getting wooed by InDesign, I just simply cannot wait any longer for QX6. For the print industry, the time has finally come to migrate to OS X and I'm giving quark 3 months to ship before I migrate our whole production to InDesign.
