Microsoft's next version of Office to use XML technology is a good thing. This sounds kinda lame, but this will open up much more flexibility for alternative office suites such as OpenOffice.Org, etc. M$'s new format will also implement the ZIP compression algorithm, so developers will basically have immediate access to do cool stuff. Isn't that what we all want?
Now we can ONLY hope that IE7 will be standards friendly and maybe M$ will be on its way to not pissing me off.
