Windows Live - and lots of gadgets
Well I've been playing around with Windows Live Messenger 8 since I downloaded it the other day and I'm really impressed with it too. From the beta page, I've had the chance to get to other beta sites to try, and Live.com has blown me away. If you've used www.start.com in the past to collate feeds, news, weather and links then you'll have a good idea about Live.com
I was listening to the keynote speech this morning and watching some totally amazing demos - and saw the link to a site I've never heard of before - Microsoft Gadgets Cool mini applications that you can use in your environment - fully customisable, and buildable and very very dynamic. There's a gallery of gadgets to play with if you don't feel up to writing your own yet. Go have a look... This customisable experience is really impressive... my page is looking good now.
