Coming from the wife of an IT guy, this is my best advice.
Laptops are cute and nice, but they are waaayyy overpriced and depreciate much like a car. In a few months they are obsolete and you will have a very difficult time selling it. They are also nearly impossible to upgrade.
A PC has alot more potential and more ability to upgrade RAM, etc and add-ons. And yes screens are better, like for gaming, etc.
We have both - a laptop and a PC. My husband much more prefers a PC.
