If you're not tech-oriented, you can hardly go wrong with an iPad. That said, if you're looking to replace a notebook (computer I'm assuming, not paper?), then you should list the the things you want to use it for. A Surface might suit you better if MS Apps (like Office) are important to you or an inexpensive Android tablet might do the trick if your needs are very simple - notes, email when you have wifi, etc.

To be clear, there are a lot of advanced apps for Android however they're not as easy to use as an iPad is.
