Yesterday, Microsoft launched the much anticipated Office suite for iPad. The suit is now available on App Store. It will cost you absolutely nothing to download for the "freemium" model.
However, there is another which is available for enterprises. That is the Office 365 subscription. This comes at a number of annual prices depending on the number of users-in a range of $60 to $264.
It simply means you can now use microsoft office on your iPad.
