That all makes sense from an experienced Smalltalker's POV.  But for people
exploring the technology the lack of native windows is usually a huge
turn-off and often reason to reject the technology.  The nice thing about
Vassili's work is that it allows one to have *both*, without losing window
state, and one can switch dynamically, and, IIRC, mix both, e.g. for
development.  So it isn't an exclusive choice.

Re VisualWorks' support for native windows it was an essential component to
VW staying in the market-place.  If it hadn't supported native windows it
would have died the commercial death long ago.  Pre-web, one /had/ to have
native windows for industry, and now with mobile native look and feel is
even more important.  Further, VWs huge lack in its GUI was lack of support
for native widgets.  We always used to tout MSWord's use of emulated
widgets (apparently for performance reasons) as a defence but it didn't
convince. The customer was always provided with poor emulations and a
limited supply.  IMO, native widgets would have made a big difference in
hwo well-received VW was for GUI applications, where those using Windows
could always turn to VSE.
