Hi Craig,
To add a bit to the previous replies. Office 2007's User Interface is pretty much a full on replacement for the one you're familiar
with.
There are new features in the 2007 version as well as refinements to the old ones, but whether those are features that you would or
could be using, or that could impact you in your work environment is something they'd have to look at. There is a compatibility
'mode' in Office 2007 that is intended to make the documents created more interchangeable based on while-working features, plus
there is also, as previously mentioned, the 'Save As' 97-2003 document format feature, that then converts some active content to
static (picture) content if it's produced by the new features, so that it's still available, in some form, to a prior version user.
You can install a 60 day trial

of the retail edition (there's also a volume license [Enterprise] featured trial available separately.
As you have more than 5 machines you may also want to look at the MS Volume Licensing provisions,
http://microsoft.com/licensing
(Open license is the 'starter set') that includes a downrev provision that could let you continue with Office 2003 on an additional
machine for now.
On the prior version side there is also the Office 2007 Compatibility/Converter pack that allows users of Office 2000, XP/2002 and
2003 to also open and save files in the new Office 2007 file formats, but it doesn't add the 2007 feature set to the older version.
=============Hi,
I was just wondering if there is a difference between Office 2003 and Office
2007, my question is are there things
you can do in 07 that you would not be able to do in 03, primarily in Word
or Excel. I have a user with 4 computers 3 with 03, we have to move the
fourth to 07 will the others loose formatting, fonts etc...?
I hope my question is clear,
Thanks Craig >>
