I have these windows in Moscow, Russia since recently (had old windows with separate wooden frames with thick glass made somewhere about 70s, they looked nice though) and like that I can use the sill as a table with laptop and tea and some stuff now, and tilt it instead of moving the laptop aside.
Ah yes, the good old Russian defenestration windows. I assume you have the FSB-mandated variant that is capable of both tilting and swinging, for.. ease of access?
