[CentOS] A few general questions

Hi All;

I ran Linux as my main laptop OS for several years, then I got into a  
mac shop and bought a macbook.
The macbook is ok but it just doesn't cut it per productivity so I've  
ordered another laptop
(a 64bit laptop with 8G of memory expandable to 16G and 2 internal  
320G 7200rpm drives)

I'll be loading Linux as soon as the machine arrives from Dell.

Here's my questions:

1) Are there any published plans for CentOS to support KDE4, or is  
there a way to upgrade CentOS to KDE4 ?

2) Does anyone know if Kpilot is working with Palm Centro phones ? Is  
there a better solution besides Kpilot ?

3) Does Kmail support Exchange yet ?

4) Is there a way to migrate apple mail messages to Kmail ?

5) Is there a way to migrate apple address book and calendar events to  
the KDE address book and calendar ?

Thanks in advance...
