I full time and have dual pane windows. I don't do anything about managing heat/humidity and I never have condensation anywhere. I don't even think about it. I don't even have condensation in my bedroom when I'm taking a shower with the bedroom door open. Early on I would run the bath power vent when showing to make sure I didn't have condensation on my windows and one day I forgot - No condensation so I don't bother with the fan any longer because it would bring in cold air.
One comment about frameless windows. If you ever have a dual pane window that develops moisture between the panes and you will over time, the cost to remove and repair frameless windows is double the cost to perform the same on standard frame windows. Repairing dual pane windows is a fraction of the cost of just getting new windows. I am speaking from personal experience here, not related to any repair facility.
Would I get dual pane windows again - absolutely.
