until you need to lug around either a heavy bulky laptop or spend a lot of money for a light one
I learned on Scroogled.com a couple weeks ago that 10" Windows laptops are back in production.
You are better of getting a cheap tablet or chromebook with a Data Plan and have your Linux running on a server where you can access for nearly anywhere.
If you're going to just use a Chromebook as an X11 or VNC terminal for a GNU/Linux VPS, how much does a data plan for that cost over the 48-month expected service life of a laptop? And how well does 3D graphics (e.g. Blender) tunnel over such a connection?
