There is a major bug with polaris office. The bug strikes at random. Basically speaking, you could be typing your lap report or business paper or english paper and all of the sudden BOOM the file is corrupted beyond repair and all your work is lost. There have been many reports, but notably several of them were of substantial loss, like someone's 30 page lab report. I've used every trick in the book to attempt to recover one of these corrupted files, and I assure you these files are truly unrecoverable. Polaris has replaced the content with jibberish data.
The kicker is this. The bug strikes may be 1 out of 100 times you use the polaris, so chances are you will not encounter this bug until later when you actually have something important.
So, please, stay away from polaris like the plague. Custom rom makers have taken polaris out of their custom roms because of this issue.
Here are a list of good office apps from market for you to get.
-Kingsoft (free but works wonderfully well)
-Thinkfree (paid - best for excel, the only office app that wil show pictures, graphs, everything in excel)
-Android Office (paid - the only one in the market with a spell checker)
-Office Suite Pro 5 (paid)
I'll add more later. These are just some off the top of my head.
Just remember, the next time 1 out of 100 times the polaris bug strike could be your 50 page love letter to your girl friend.
