You know who likes all of your files to be stored in ‘the cloud’? Google...and hackers. Suck it up and get a real computer, then never use the cloud. I knew my thinking was correct on this when Steve Wozniak expressed his opinion on cloud storage.
Chromebooks are a great little web browsing and media streaming device around the home. I’ve used them for years. Wouldn’t want one exclusively for work.
A Chromebook works best when you don’t have any files to be stored in a cloud.
I agree that if you have such files that are important a real Computer is the right choice.
