I just bought a new laptop. I have had several Toshiba's and they have been good for an off the shelf pc and pretty rugged. This time I ordered a Dell Latitude because I use it for my business and wanted to customize it with certain hardware features. I wanted the latest chip(Intel I7). You want to get 8 GB of Ram these days, you will need it and it is cheap and probably more important than getting a giant hard drive unless you keep lots of video. I have Windows 10 on that machine and on a desktop(that was upgraded from 7). It is new and different but is a good operating system and is easy to learn. If you use Office and are only using it when connected to the internet, then 365, which I have on my desktop and is at home, is a good option. It is around $60 per year and comes with a terrabyte of storage on One Drive, which is pretty cool and gives you access to whatever you store there(in my case, pretty much everything) on any of your devices, and it is also a redundant cloud back up for me. I bought Office 2016 on my laptop because I want to be able to use it even if I am not connected to the internet. If I was buying a home machine, I would look for something around $6-800 and get the fastest chip I could, I think you can find one with an I5 at that price range. Your battery time can also be important, you probably want to look into that. I like to get around 4 years out of them, so in my case and because it's primary purpose is business, I spent more money to get exactly what I needed instead of making do with what came with it. There are some good hardware suggestions here already, they will be dependent on your budget. Less expensive machines will tend to be heavier. Acer and HP both have nice machines also. And think about if you need a cd drive, my latest does not, another weight saver. I have found I only use the cd drive on my other machines to install software and that is rare anymore. I will buy an external one to have around, but don't need to be lugging it around on the machine. The best thing you can do before you buy is make a list of what you use it for, and take that with you when you go shopping, it will really help you narrow down your choices.
