Windows XP - Pro or Home?

["Ho Yin Ng" <architect.hoyin@xxxxxxxxx>]

I need to buy another copy of Windows XP.

What exactly is the difference between Pro and Home? Do I need to
spend an extra =A330 to get Pro? Is the price at ebuyer good?

Also I have a Fujitsu Siemens laptop with Win XP installed on it, but
I don't remember it coming with any windows disks. What happens when /
if I need to do a reinstall?

What about serial codes etc?

Thanks
