How long have you been running Vista for on your desktop (honestly)?  
My desktop is what my notebook PC sits on :-)  I have a seperate HDD with Vista installed that I swap into and out of my primary notebook PC- an Acer Ferrari 4005. It's a great machine for running Vista as it has good driver support and a 64 bit chip. It's also Red and Carbon Fibre so it matches my Ferrari Replica Pit Crew shoes :-)

I'm pretty well commited to going to Vista full time from Beta 2 onward. Once we get Beta 2 of Vista and Office 12 I'll be making the switch completely.  At the same time I'll probably have a punt at upgrading my tablet and my Windows Media Center as well.

Tell me about a Vista feature have you discovered recently.  
One of the coolest features that I've seen on Vista is the speech recognition stuff.
Once you get speech recognition baked into the OS it really does mean that it goes from mere dictation to a fully fledged human interaction device.  I really enjoyed watching this screen capture video:

You’re co-presenting in Auckland; do you know which topics you’ll be talking on yet? 
I've not completely locked down the topics I'm doing yet. I'll probably do the Windows Workflow stuff as that's something my company and myself know quite a bit about. I'll probably also try and do some of the WPF stuff.
 
Who is your favorite Australian cricketer?  
Ha ha....  My favourite Australian Cricketer would have to be Shane Warne. Why? Becuase he's so genuinely 'Australian'.  But honestly, you guys have had some complete crackers when it comes to sports people- David Boon, Shane Warne, Wendell Sailor.  Hope you watched the Warratahs lost to the Hurricanes on the weekend.   
 
Finally, it would be fair to say that not many people have installed Vista and played with it in anger?  Do you have any feelings about why people will jump in for Beta 2?  Do you think that there will be a big shift by users in Beta 2?
 
Yup. I agree.

Beta 2 is generally regarded as the point in the MSFT build cycle where you get something stable enough to work with every day and where you get a broader public release. Obviously the more frequent CTP build approach they've taken may have moved the goal posts a little on this but I'm confident that Beta 2 is going to be stable enough and locked down in feature set enough for me to make it my primary OS.

There is obviously going to be a HUGE shift in users onto Beta 2. It is likely to be a public Beta (I think) so you'll obviously have it in the hands of a broader range of users that the previous CTPs and Betas. I think it'll also be the build in which the numbr of hobbyist and enthusiasts really starts to ramp up onto it.
