Just been given full Office 2007 by Microsoft (Yes, Big Bill does occasionally give away things to paying customers that don't live in the "Dark Continent"!!!)and can't make my mind up whether to upgrade from Office 2003. Suggestions/problems would be helpful.
I tried 2007 when it was sent out for general trial. Personally, I've stuck with 2003 - it does all I want it too. But, if you have had a program for free - which you normally have to pay through the nose for - go for it!!
If you don't like it 'cos it takes time to learn and unlearn 2003 at the same time (as Python33 says) then you can always save any files written in 2007 as plain .doc files (similarly in Excel change any files written to .XLS) - assuming that in each case you saved them in their new format.
Assuming you've got a 'full' copy and not an upgrade. Install Office 2007 alongside Office 2003, you can use both sets of applications alongside each other if you so wish. I've done it and all works fine.
Only Outlook cannot exist in two formats - and you have to chose either 2007 or 2003.
Used the software since February, and I'm impressed with it. You have the new format .docx, .xlsx, .pttx, .dbx etc - but you can save in the older formats to maintain compatibility with older software. Also, you have the opportunity of converting older formats into the new style as well, with minimal change of layouts - the programme warns you when this may occur and how.
Generally, I found the software very easy to use - the new edition of Word is great and very intuitive, and the new style wizards and templates make documents look very effective. The new format saves in a smaller file size which is also handy for e-mail attachments.
