Not one of the usual "windows" posts we sometimes get on here.
After a lot of deliberation, windows are what I have decided to buy instead of selling my 2.5si and upgrading to a Z4MR. Lovely wooden sash windows - two of them and two patio doors. They have easy-open top lights and BSI-approved security bolts. I am comfortable with my decision.
