The thing is, everything I bought don't use those ports. I have to buy a new keyboard and a new mouse (wireless mouses also need a driver dongle) for the ports.

And what is worse? New laptops have less ports than the older ones. That 5550 only has 3 ports and 1 is for charging. If I want to mount an external hard drive, I need to bring a hub.

What again, looks like everyone is doing that, so yeah, better embrace it.
