Cool! Apple is sure making it easy for me to keep my Contacts' information all over the place. On my phone, on the web - I love it.
On the PIM front, I've been using a trial version of Inbox Buddy for a few months now. This software rocks, and it makes my e-mail addiction soooo much easier to cope with! Do you have a cluttered Inbox? If so, you should really try this out, it's amazing how it works so well - and only $30 when you finally decide to buy it. I bought it yesterday.
