Very good!
The best office suite on the apple store, to my advice.
Ive tried the other 2 main competitors and this app outperform them in terms of functionality (graphs, editing) and compatibility.
The connectivity is also good, I mainly use Dropbox and google docs, both supported.
To get a 5th star you can still improve the UI, which could be more friendly (what about double-touch to edit on all objects? And entering formulas in excel sometimes require a few too many movements) as well as fix a few glitches.
But these are minor issues and overally speaking the app is worth its tag price.
So very good, please keep refining it!!!
