How seamlessly can you move word documents, excel spreadsheets, and powerpoint presentations from Office '11 for Mac to the iWork suite on the iPad? Would you lose a lot of the formatting, charts, etc? I'm using the free trial of Office and I plan to buy the iPad 2. There are a lot of advanced functions, formats, charts, etc and I'm trying to decide how these would convert if I opened them on an iPad. Maybe quickoffice or docstogo works more seamlessly with Office '11?
