You have?

I'm on a list which has users of SLES and of RHEL (and slack and debian) 
on zSeries. I don't recall anyone sad to use ext3, but there have been 
the occasional stuffed reiserfs. Then there's the real concern the 
development team for reiserfs is small and has some legal difficulties 
that may seem him operating for several lifetimes from inside a US prison.

You need something that understands both filesystems. Reading NTFS in 
Linux is fairly straightforward, but on CentOS you will need to download 
less official kernel modules (each time you upgrade the kernel) or 
rebuild each kernel. Neither is difficult, and the need evaporates when 
Windows is out of your life.

An extra drive won't strain the budget so hard, and gives you a neat 
backup device.
