Development

I am going to buy one of the smartphones, but I want to know beforehand if it will be compatible with my Macintosh ibook to the extent that it will hotsync my itunes, icalendar, iphoto and my email address book. I want to simplify things - have one phone that is compatible with my computer.
This is my first time on the forum, so please be patient with me if I've put this in the wrong spot or the answer is elsewhere.
Thanks, everyone.
