> The basic disadvantage of that design is that a real radio or TV can change channels in milliseconds, but it takes seconds to set up a digital stream in most cases. Only for tuned stations. If you’re scanning the frequency (which is what the up and down arrow remind me more of) then it will take as long as it takes for your tuner to find the next station along. And that’s assuming you even have an automatic tuner, my first radio could only be manually tuned and didn’t support presets.
