partitioning - How should I partition my Ubuntu 10.10 install?

I have about 12-15 GBs of disk space on which I am about to install Ubuntu 10.10.

I am considering following partitioning scheme:

14GB partition with 10GB root, 2GB swap (I have 4GB RAM) & 2GB home

People say to keep a partition /home, as it will have backup of my user setting and useful when i upgrade, is that correct?

Kindly guide me if this is okay, or suggest a different partitioning scheme.

Thanks.
