Hi,
Someone on the previous page just asked a similar question and here is the answer I gave.
There's an app called Jump Desktop (Remote Desktop) in the app store. It's the fourth highest 'paid' app and the third highest 'grossing' app in the business category. (Go to the app store, then click on categories, then business. Then over on the right under top grossing and top paid you can click on Jump and read the reviews.)
You'll be able do do more than read the documents if you want. You can work from your ipad with documents, spreadsheets, etc., make changes in them on your ipad and they will be reflected on your computer (mac or pc.) And you don't need a cellular ipad to make the connection. All you need to do is have your MBP on at home with a wireless network and be in an area where you have wireless access to connect your ipad (or iphone) with your MBP at home.
Jump Desktop (Remote Desktop) RDP/VNC will let you access your mac and all of your mac programs like MS Word, Excel, etc., as they are on your ipad. There's a free trial at jumpdesktop.com. If you like it you can then come back to the App store and buy it. Please note that there are many free apps that will help but you might have to spend extra time adapting your work to an ios app as many (most?) do not translate from mac to ipad well.
Please read the reviews in the app store (I suggest you start with the most recent ones) and read reviews by pro tech reviewers.
Hope this helps.
