I have no idea where this sentiment is coming from. I'm typing this from an MBP with a das keyboard, navigating with a razer mouse and viewing with a samsung monitor, everything works fine.
All keyboards are the same, all mice are the same, spectral analyzers are not the same, software-defined radios are not the same, USB-Serial adapters are not the same, FPGA interfaces are not the same, sensor boards are not the same, laser cutters are not the same, need I go on?
