Yes - that's an excellent way to put it. Make zoom work like it does in a desktop browser. The one thing I can appreciate though is double tap to get rid of cruft by focusing in on text.

Not exactly, but that's closer. Use Opera for Android to see what I mean. Be sure to enable reflow related options. It's pretty great.

The difference is mainly intelligently limiting DIVs (columns) individually to the available viewport horizontal space. Ctrl-plus and Ctrl-minus does not do this, it tries to fit whole width.

Shame that other mobile browsers have made it their mission to imitate whatever mobile Safari is doing.
