I manage a lake in Kansas that has 20 RV Sites with hook ups, 21 Piers for camping and 2 large grass areas for camping. I got the iPad 2 to eliminate the amount of paperwork that was building up very quickly. What I would like some help with is deciding what the best app is to to make spreadsheets in ( preferably able to be emailed to a PC and opened in excel). I also need to be able to open read and manipulate word documents on my iPad from time to time. Please help as soon as you can I need to start utilizing every aspect of this device and I can't pick the best ones. Thank you for your time and look forward to hearing everyones advice, I need it.
