The Microsoft Excel for the iPad may not really give you much of a boost if you are a financial analyst. The Excel for iPad will not tempt you away from your four-monitor desktop, with your Bloomberg or Dow Jones feed in one monitor and excel running in the other three. However, if you are simply doing straightforward business projections or keeping track of your finances, excel for iPad gets the task done more elegantly and expeditiously than anything else on a tablet. The app can be freely downloaded, but that solely permits you to read documents. If you would like to unlock the complete document-editing features of excel for iPad—or its suite-mates, Word for iPad and PowerPoint for iPad—you’ll need a subscription to Office 365 $63.15 at Amazon, which generally costs $99 for customers.
