Personally, I think there's no point spending massive amounts of money on JAWS over NVDA for basic screen reading. JAWS is helpful if you need specialised scripting in a workplace or are using advanced features of Microsoft Office, but for the basics like checking Email or browsing the internet you're going to be getting a similar experience except without the upfront cost or software maintenance costs that will come afterward. If you do want to spend money on something, maybe have a look at Dolphin Guide Connect, which is built mainly for elderly people losing vision. It's basically a suite of applications letting you do the most common things on a computer - read and write Email, browse the internet, read news feeds and newspapers, write and print out documents, read and listen to books, as well as play music. The menus are incredibly simple to use based around a task system. so they're presented kind of like a phone menu with prompts like "To read your Email, press 1. To browse the internet, press 2..." and so on. At the same time, if she's comfortable using an iPhone it's perfectly capable of performing a lot of basic tasks on its own as easily if not easier than a computer. Have a look at \[Applevis\](
$1) which offers beginner guides as well as a massive list of accessible apps, including a list of good apps for getting started with an iPhone.
