I don't use parts (yet) and the apps I've made are between 1.3Mb and 1.8Mb
when optimised (aka "minimised" or "generate build" in qooxdoo) and while
the first access has to download that big file, subsequent startup times
are within a second or two.  That big size would be a problem if lots of
new users were always signing up for the first time, but if your users are
well-known regular users then its not a problem.

>>- desktop like

Yes, that's the big benefit of Qooxdoo IMHO, that it allows real desktop
development via a browser.  Development tools for large desktop apps (like
"real" OO and rich GUI widgets) that we had in the 90's are finally here
in the browser in a consistent, supported platform.

There's also more and more evidence to justify that IE6 support is less
and less worthwhile (try http://www.ie6countdown.com/) but the key thing
is to know your users, and that will tell you whether you need to support
IE6 (or IE7).  One of my customers is still running a Qooxdoo 0.8 app, and
about 3 years ago they agreed to ban IE6 & IE7 completely - the website
won't even let you log in with IE6; it was a difficult decision at the
time but we pointed to security risks and corporates like paypal and
youtube that had removed support for IE6.

Having said that, it was only because we found an obscure bug under IE6
that forced the issue, i.e. it was easier to drop support for IE6 than try
and fix it!  Otherwise the app was slow but worked fine.
