A:AnswerWhat I can tell you is we have Office 365 installed on both our iPhones and iPad (5th generation) and it works well. So if it works on these devices I see no reason it would not work on the Pro.
A:AnswerYes. Pages is similar to Word, Keynote is similar to PowerPoint, and Numbers is similar to Excel. These all come preinstalled on the iPad. Comparable Apps are also available in both free and "paid for" versions. The Microsoft versions of these apps are also available for iPad but cost quite a bit more than similar apps in the App Store.
A:AnswerI don’t know of any discounts right now, but depending on where you live you could get a great deal. They also have price match, so check around. Good luck!!
