I agree.  The UI for AOS is built on XML.  Yes
there is still an "Oberon compatibility mode"
also.  Unfortunately the UI for AOS hasn't been
finalized yet (at least not that I can tell).
There is work yet to be done.

Beyond that I would say that XML is essential
because it opens up so many other possiblities
like WebDAV and XMLRPC.  Also it would be
possible for someone to write a Jabber client
for Oberon and that would allow someone to use
instant messaging from Oberon and connect to
AIM, Yahoo IM or MSN IM.

In other words the AOS PPP module is buggy?

How do you connect to DSL throw AOS?  Are you using
a USB connection, or a connection from an ethernet

The V4 (and BlackBox) folding mechanism is more 
powerful than System 3 outlines.  Outlines simply
let you "collapse" text.  Folds actually "toggle"
between two texts.  One way I've seen this used
is a type of "literate programming" scheme where
"folded text" shows long comments and "unfolded
text" shows program code.
