to ext4 or not...

Hi Guys,

I just upgraded my desktop to fedora 11. The way I set up my system is 
with my home directory in a separate partition so that if I want to do 
an upgrade by reinstalling fedora, I can then reformat / and /boot 
leaving /home directory is untouched.

But now there is ext4. So, should I leave /home as an ext3 file system? 
Or should I go through the trouble of backing up /home, reformatting to 
ext4 and restoring? Currently / is now ext4.

Thanks. Steve.
