Synchronizing laptop and desktop

Hi,
I just saw this section, so decided to post my question here as well as
networking... Not sure which is better for this type of question.
I have a desktop running Vista ultimate, and a laptop runing Vista home
premium.
I would like to sync the desktop and the laptop together.
More specifically I'd like Outlook 2007 to be synched and a specific folder
on the harddrives.
Is this possible? I simply want to create a partnership between the two, the
same way I would with a PDA. Ideally i'd like this to sync over wifi at the
touch of a button.
Please let me know,
Thanks!
