The biggest thing our users want to do with a tablet is a 'real' PowerPoint presentation. If we could find a solid PPTx presentation tool many users could dump their laptops as tablets handle e-mail, browsing and other travel functions quite well. Kingsoft is pretty solid in this regard, but still struggles a bit with more complex presentations. You cannot access links in the presentations or embedded video/audio (made sure the video/audio file was in same folder as PPTx as well). If your presentations are just static slides it likely will work well, but so would a number of other Office suites (or converting your slides to JPGs or a PDF as well).

We also had a difficulty using BOX.NET accounts. We tried a few different ones and could not log in through Kingsoft, but could get in using the BOX app or through the browser. Not sure what the hiccup was, but it definitely minimizes what should be a really slick feature.

The interface is really nice - defintely the closest to a desktop Office suite that I have seen on Android. I could see using this suite more than our other favorites if compatibility holds up as we throw more files at it. If PPTx abilities were enhanced it would easily become the standard on all our Android devices.
