So, when I got my N7 I looked around for a good "Office" type app. Kingsoft Office rose to the top real quick since it's free. OfficeSuite is highly-regarded, but it costs $14.99, and I decided not to spend the money.
I've been using Kingsoft for two months now and man, does it suck. I realize that there are plenty of good reviews for that app, but those users may not be using it as frequently as me, or maybe they are working with 1-pagers. Otherwise, anyone really using Kingsoft has to run into the same crappy unstable and unpredictable behavior that I've been living with - it's so pervasive in this app. One frustrating example is the backspace function. It might do nothing, it might delete a letter, or a word or a sentence or a bunch of sentences. Then, when you begin to type the words back in that it deleted, the app will begin to toss in some parts of the words it deleted. The app doesn't reliably call the keyboard when you tap in the doc. There's more to dislike, but I'll just stop there. The Devs are totally non-responsive, BTW.
In a fit of Kingsoft rage the other day, I bought OfficeSuite Pro 7 and I wish I had done this earlier. It's not that OfficeSuite is just better, it's in an entirely different league. It's beautifully designed, the UI is perfectly human-factored. It's fast, offers every function I can think of, and best of all, it's freak'in stable - like 100% stable. Integration with cloud storage is fast and reliable.
If Kingsoft is your favorite Office app and it works perfectly for you, then life is great - for you. For me, IMO Kingsoft is not ready for prime time.
If you've been on the fence regarding shelling out the $14.99 price for OfficeSuite, I can tell you it's worth it. It really is an awesome app.
