What device is best for reading PDFs locally?

Episode 1199 (1:23:30)

Steve from Dana Point, CA
Apple iPad Mini

Steve is looking to get an iPad Mini, but he doesn't want to use the Cloud. Can he avoid accessing his data on the internet? Leo says that because Steve is using Quickbooks, he'll need Windows for it. Leo advises going with the Microsoft Surface Pro or Lenovo Yoga. It'll also be beneficial for word processing.

He wants something pocket sized, though. He can use Quickbooks online for the iPad, because it's a cloud version. But then he's running in a browser, in the Cloud, which is what Steve doesn't want. The Surface 3 is fairly lightweight and can do PDF and some word processing. But if he's going to use the ipad, he should use iBooks for his PDF reader.
