I'm thinking of replacing my very old Dell PC (windows 7 premium) with a laptop, which I use for business. Looking for something that's fast and maybe offers more storage than what I have. ( I currently use 165 of 286 GB) I don't do gaming, videos, etc. .....it's mostly lots of documents and I'm on the internet all day. Any recommendations? I've done some research, but everyone has a different top ten list. Was thinking of looking at Dell XPS 13, Lenovo ThinkPad x1 carbon, and Microsoft Surface Pro 6.
