Unless you have a 2 way camera system, a window isn’t redundant. At best, it’s equivalent to having a one-way mirror. I record others and as well as by myself and even when alone, the window is incredibly useful for when I need to see my physical console, meters, preamps or the DAW screens for any reason. I’ve tried streaming video but realized it was an unnecessary resource draining my DAW and also unless it is a 2 way video system, it really isn’t as effective as a window. When tracking bass and drums live, 2 way visual contact between performers is really important. That means less mistakes and more productive sessions. Oh and lastly, the window looks cool! lol Just my 2 cents.
