@johnpowell A Luddite with a Facebook page? :D
Seriously though, tablets in general are good for that. For basic use (opening apps, playing games, net-surfing…), both Apple and Google did a good job at simplifying things to the point where literacy is not required; a toddler can figure out how to do those things. Many professional reviewers agree and now consider both iOS and Honeycomb (Android v3.1) tied for ease of use.
The tricky part is getting the apps on there in the first place, whether you use iTunes or Android Market. Both platforms allow you to install apps directly from the device, and both do so in a very similar manner. Of course, that also means a little bit of learning, but it isn’t too hard. I only mention it because I know some people who get an i[Pad/Pod/Phone] or Android tablet/smartphone and somehow or another fail at finding the market.
Also note that there are really only two viable competitors to the iPad 2; the Motorola Xoom (which has it’s own issues, and thus I am not fond of), and the Samsung Galaxy Tab 10.1, which I will detail a bit just to show you that there is an alternative. But first, here is a side-by-side comparison between the Galaxy and the iPad 2. Feel free to ignore the numbers and focus on the text; also note that the reviewer was a total newbie when it came to Android.
If you are into screen size, the iPad has a 9.7” screen, but the Galaxy Tab 10.1 has a 10.1” screen, and a sharper one at that. Whether or not it is more legible… well, I find it to be, but it might be best to see for yourself.
If any of the sites she surfs to have video, the iPad may get iffy. If she runs across a site that uses Adobe Flash, an iPad simply won’t show it. While those issues are going away as Flash gets phased out, I go enough places that use at least some Flash (especially those with interactive images) that an iPad would leave me looking at a lot of white space where content should be. Depending on where she goes, it may or may not be an issue for you, but it is worth mentioning no matter how some people try playing that down.
Both are comparably priced, the Samsung is a hair lighter (but not notably so; less than 1½ ounces), the iPad has Apple (best customer service in the industry) behind it, both can run off of your existing wifi connection, both are simple enough for my cat to figure out… all in all, it really is a toss-up as to which is objectively better. I thought the extra 0.4” of screen on an otherwise comparable device might suit your needs better, but if it doesn’t, c’est la vie.
