MacBook Airs are specifically for browsing. Don’t worry about the MacBook haters, they play Arma 3.
I picked up a Microsoft Surface years ago and that thing just sucks. I sold it due to how laggy it was getting.
I’ve had my MacBook Pro 13.3 inch for literally four years and it’s still stellar. Bright screen due to the backlight they use, fast as can be, perfect for work.
They also make apple refurbished which is basically brand new due to Apple’s standards.
Don’t fall for the laptop gaming meme though. Just get a compact if you want to game, laptop gaming is just stupid. The time it takes to set it all up you’re going to need a bunch of random stuff to enjoy yourself on a game like Arma.
