I just finish building mine 2 days ago with a budget of 700 for the PC and 300 for other stuff like keyboard,mouse,headset, and a monitor ect... just so I can play Fallout 4 this November lol
Not a big fan of technical mumbo-jumbo and laptops are too small for my taste. I do have a tablet, but I only use it to read downloaded books and comics.
Laptop I may treat it like a desktop but I like having the option to be mobile if need be. Helps that it has no problems playing games at their highest settings.
Me, I use pre-built laptops. Haven't had a desktop since I was like, what, 10? Don't quite remember. My family travels WAAAAY too much for my liking, so when they drag me along I like to have a portable computer, so I use laptops.
I don't even know where to start with custom builds because I'm not that savvy with electronics. More of a software guy than a hardware one.
