For how long is the trial version valid before it stops working?
On the Microsoft website you have to log in to get past the topmost pages to find out (unless I've missed it) and I don't want to register there if it's not worth continuing. The home version is what I want but I would be surprised if there are different durations for the various versions.
p.s. I already have OpenOffice so don't bother suggesting that as an alternative, I fancy giving Office a go.
