If you want to downsize to just one computer, do you really want it to be a notebook? Contrary to what the notebook maker's marketing weenies would like us to believe, notebooks do NOT make great "desktop replacements" or gaming machines.
The problem is, they can easily pack PC power inside those tiny, super thin notebook cases, but they cannot pack the necessary cooling to allow all that hardware to run at full potentials all the time. If you think about how much of a challenge it is with regular PC cases (with multiple large case fans) to keep our heat sensitive devices cool, it is no wonder notebook cases are simply incapable of that task.
Plus, with a PC case, you can remove the side and perform deep cleaning to rid the interior of all that heat trapping dust drawn in by the fans. Thorough cleaning of notebooks interiors is just as critical, but nearly impossible for most users.
Also, notebooks, especially ones that travel, get dropped, left in sizzling hot or freezing cold cars, banged around, left behind, or worse - they grow legs and wander off when left unattended - for just a few split seconds. If you have just one computer and it goes missing or breaks, you will end up a vile creek without a paddle. Even with a current backup, what good is it?
So at the very least, I would urge you to keep at least one PC to use at home, at least as a backup device for your data.
