This is a super-frequently discussed topic among electronic musicians. No question software has become dominant, but I think the main argument for why hardware hasn't been "wiped out" is more or less what you said - interacting with a dedicated piece of hardware with knobs, faders, keys is a very different experience than typing and clicking or tapping on a touch screen. You can use MIDI controllers for PCs/tablets, but it's still not quite the same, as you have to configure your controller for each plugin, etc. There's some advanced controller interfaces like the Maschine that have a deeper integration between the software and hardware. But then you're still tethered to a computer, which some people dislike.
