Chromebooks
I have one and I like it for certain things. They're light, cheap, boot up very quickly and have good battery life. They're great for doing email, facebook and web surfing.
What they are not good for is working on pictures - the processors are not fast enough and they have a very limited amount of RAM that you can't add to.
Most of them don't have a hard drive that anything other than their small operating system can be stored on. In other words if you want to store anything you need to do it on an external device like a thumb drive or Western Digital Passport drive. The other option is to store your info in cloud storage which isn't too good for some of the places you may travel to. A few chromebooks do have storage, but it's very limited. Don't try to work large megapixel pictures on a chromebook.
I don't think you can buy laptops with Windows 7, 8 or 8.1 anymore. You might find an older, but still new, laptop with windows 7 on it. Most likely you'll have to buy one with windows 10. I did and I don't like it at all, others like it.
If your wallet is strong, I'd look at Apple instead of something with windows 10 on it.
If you have a Best Buy handy, go in and look around. They've been doing a good job of training on their people in the last year. When you find something you like, check the internet for pricing and they'll match it.
The good part of buying it from BB is you get it right then at the same price. The bad part of BB is you only get two weeks to return it if you don't like it. With Amazon you get a lot longer return period.
