Update:
Even with Microsoft releasing Office for iPad, this app still has a few things doing way better.
----
Its not MS office but pretty good - with exception Doc editor.
Sheets and presentations editor are excellent but the document editor (although many great functions) it lacks behind Office2 HD - by miles.
For 1 dollar you should grab this. I paid 20 bucks, bad I didnt wait for a few days. Its worth it though.
DocsToGo goes to trash, in case you still use it, Polaris can hide and unhinde columns.
But as I said, doesnt replace Office2 HD.
UPDATE:
The integration with Dropbox and other services is very complicated and doesnt make any sense. Its absolutely complicated to copy anything from Polaris Office desktop and save it to Dropbox. Forget it. Its all nice design work and the 2 pane view is good, but it should take so many steps to get there. It should be more intuitive.
