Hi welbeck.
First of all, how nice to have a friend who thinks so much of you as to give you such a lovely gift!
It seems that most of what you need to do is online stuff, on the internet. If you don't use Word, or Excel, or anything like that, the Chromebook will do you fine.
The Asus C523NA has a much bigger screen than an iPad, so that shouldn't be a problem. Your friend must have chosen to have all her emails on screen all the time, that doesn't have to be the case. So you can choose if you want to do that or not. You can also use a wireless mouse or an "old fashioned" mouse linked to the Chromebook by a wire, if that's what you want, so the touchpad doesn't have to be a problem either.
It sounds like the laptop you have is very old, since its still on Windows 7. Eventually, it will unfortunately grind to a halt, that's what old laptops do. So why not try your new Chromebook, and take your time until you understand it all? Use both of them for now until you feel comfortable with the Chromebook. You'll be able to put your favourite websites into your "Favourites", and access any other website you want.
Try to get some help to get you started. You probably don't need classes at the moment, just somebody to set you up so that you can do all the things you want to. Why not try the library or something similar to see if there are people who can help you out, on a voluntary basis?
Good luck!!
