Sync iPod Touch to second computer

[wolfe]

I have my iPod touch, Outlook and my one computer synced perfectly.

Now I want to sync my ipod to my second computer so Outlook and iTunes are exactly the same.

When I hook up the ipod to the second computer (under the Summary tab "Manually manage...box checked) I have a "Sync" option. But when I click on "Info" tab and check sync Contacts, etc I get an "Apply" button instead of "Sync".

Want to make sure I don't make any changes to the iPod.

What should I do to sync to the second computer?
