I just bought a new PC, based on Lenovo Legion gaming desktop. It comes with 2 USB port in the front, 4 regular USB port in the back + 1 USB-C port. That’s a total of 7 USB slots.
It’s been like 2 decades that every possible hardware device comes with an USB interface. Keyboard, mouse, joystick, hard-drive, memory stick, headset, webcam, spot/photo camera, and many others.
Of course it’s my fault, I should have thought about USB connectors when shopping for a new PC and check before buying. but seriously, 7 USB slots is so few compared to all the device I have using USB
In my experience the latency on Bluetooth mice and keyboards is so low that it doesn’t matter. Most people who aren’t playing in like the top 1% of their game should be fine.
