I build my own PC's, and for something portable I get a tablet for $100 or so and just copy whatever I need to it if I need to travel. Never liked any laptops I ever saw, and don't know anybody who did own them who didn't have trouble with them all the time.
You never had a problem with a desk top? That's astounding!!!!!
Nope, just a power supply going out once, after 4 years, replaced, lasted another 6 years and went out again, but they had quit making supplies like the old one, so I built a new one. My first PC still works, it finally just went obsolete and I built a new one, which also still works fine, just went obsolete also; current one is going on 7 years old and has only been turned off a couple of times in its entire life, due to a blackout during a storm, and being moved to another room and cleaned; I'm one of those who never turn theirs off and on, as that wears them out quicker; I just leave on 24/7.
Laptops cost 3-4X more than a PC that has much more capability, even with the cheap memory these days; they run hot and don't have the lifespans, and still most have crappy batteries. A decent tablet is much better for the money, and stuff is easily downloaded to them from a PC or copied to a PC via merely drag and drop over USB ports. No need for over-priced laptops. A very good reliable PC can built for less than $300 if you scrounge, or built off the shelf for $600 to $1,000 these days, a tablet for $90-120.
