Can someone explain to me, in laymans terms the differences between Microsoft Office 2007?

I am looking at getting the home edition, for 99 pounds, but what am I missing compared to the proffesional edition which retails for over 250 pounds? I had a beta tester of proffesional, and really liked it. I am a home user, occasionally using for Word and PP Presentations. Any Advice would be very much appreciated.

it has a word proccessor and

finance suite installed (on disc)

ok for busy company's

but too much just for a personal

home user,u can purchase similar

software and install on xp home

that will suit the ordinary user

for a lot less money,in a nutshell

xp home has a bit of everything

ie:entertainment,file management,photo editing.

xp proffesional or office is more for serious

computing.
