There is an argument for both but, if you go with Chromebook you are pretty much using an app based device, all good some say. However, bear in mind that some software is less user friendly in app format.
I was very keen to get away from Microsoft when I looked for my latest laptop and going with Chrome could have made that decision easy but, I looked at what I would have got and reluctantly decided that I still preferred the way software on the laptop worked.
I can still make my minor protest by not using a lot of Microsoft apps but some are still better than the alternatives.
A more technically adept poster will come along with a more reasoned argument either way (wait for someone to come up with Macbooks etc!) but, I am happy with my choice and can still use my tablet/phone for Android stuff.
I went to Dell in the end, got a much better deal on line than via retail (Currys/PC world) and am very happy with the result.
This article from C-Net is quite informative:
Sure, a laptop has more functionality, but maybe you don't need all that.
