I will never use it for anything more than what I listed. With that said, is the base configuration enough for me and should last me 5 or more years? I have been reading on the topic of RAM and so many people are saying "you need 16GB of RAM, you never know what you will want to do on the machine in the future, and you need 16gb for this and that, etc". All the stuff people mention doing, video stuff etc I will never do.
You'd be far better off with an iPad and a keyboard/trackpad case to be honest.
To use the Steve Jobs analogy of about a decade ago, using a laptop for this is basically using a truck (or maybe a helicopter; that's more dangerous) to go get your groceries instead of a car.
The iPad is a safer, more portable web browser, a MUCH better e-book reader, has better cameras, consumes less storage and you can get the keyboard of your choice - which is easily replaceable if you damage it.
A base model iPad or iPad Air (if you want 13" screen) would do the job for you, maybe just bump the storage on that to 256 GB.
The iPad will also double as a note-taking device if you get a pencil for it down the track. You can also use the pencil to fill out PDF delivered forms in your email and send them back without needing to print them etc.
