I tried DataViz “Documents to Go” on my Droid. I had used it on various Palm devices and it is a great program.
The current version (2.003) would not show my spreadsheets correctly. I use spreadsheets mostly for scheduling and keeping records so they are long (300 to 500 rows) and narrow (3 to 5 columns) with no complex formulas.
The DOC program and PDF viewer seemed to work fine (I bought the full version) but the spreadsheet viewer scrambled my columns and rows in a strange way. I asked for and e-mail confirms I received a refund.
Anyone else experience this problem? Is it peculiar to Android 2.0?
