When working this is great- but the web shows lots of people who have had troubles with this system.
Some bits of learning!
eg once set up- bottom right of your screen, in windows vista (or XP I suspect) right click on the google sync icon, and one has the option to sync straight away. I have been very happy- mostly- with the one way sync from computer (outlook 2003) to my web site.
You need a google account first.
