It's a bit ironic how in the same breath you go from "it's impossible to build apps for multiple resolutions with drag'n'drop hence web" to "software and their UI has become more complex".

While the absolute vast majority of web-based software cannot hold a candle to UIs you could trivially build in VB (or Delphi and other RADs). Most web-based software is either trivial forms or a few screens of text and images they struggle to display with any acceptable performance.

As for "many different resolutions and screens", have you ever, I don't know, resized a desktop window? Desktop apps work at the number of crazy sizes the web would die at.
