Phones for Mac that sync wells

hi:

i am a new mac user. i have to say, OS X is a much better OS when Windows is.

however, i am facing one problem. i like to keep my appointments on my phones and alarm/remind me.

i am using a windows mobile 5 pda phone. however, "the missing sync" or "pocketmac" don't sync that well.

i would love to have a phone that sync well with iCal, address book and all.

what are some of the phones that sync well out there?

thanks

Here's the list:

Sony ericsson phones generally integrate with OS X really well.

I have an "Old" Z600 from SE sync is just great via BT
