From my own point of view, I'll be posting on a whole range of things - I hope - including mobility as it's still a passion of mine from a technology point of view but so is Vista and Gadgets and XBOX and MSN and a whole bunch of stuff related to Microsoft.
There has been a lot of dicussion about Office 12 and PDF recently and also the XPS format (aka Metro) - XML Paper Specification. Jeff Bell has a lot more info on his blog
I'm still getting my head around XPS but the notion of being able to exchange documents in a final form and having many applications (and OS'es) be able to natively view and print them sounds cool. Check out the Metro fact sheet
BG being Bill Gates - check it out!
Bill was in town (London) last week and on great form. We get to see him present a reasonable amount both live and via recordings etc and it's always great when he does live Q&A from the audience. The BBC also got to interview Bill where he talked about some similar things such as competing with Google, Sony and others. Bill must have dashed about a fair bit last week as he also spoke with The Guardian and when I got the tube on friday I was pretty shocked to see that Bill was front page in the Metro!
