You are correct Gary I stood for 30+ yrs and until I got smart and my legs, ankles, & knees told me it's time to sit down and play, no one wants to see some fat guy standing and swaying his but around trying to look kool! ......
good thing I listened to my body
As far as the glare on a fixed screen it really sux when your a very low sitter under overhead recessed lights, or outdoors. etc,...most time a second tier shelf or sun enclosure was needed to see the display. I enjoy a Tilted screen for sure.. sheeesh even my old Tecnics KN5000, KN6000, KN7000, Tyros, had Tilt displays...
stand or squint if you like but it's NOT for me ..

all the best
