Well, this is the Ultimate version with all the programs you want and I think the price is really fair, so I wouldn't hesitate to show them my appreciation for this, in fact I bought it on Sunday, heh.
It's my first office as well(since it's the first time they offer it at a reasonable price) so I got no big problems with the user interface, even though it's different from OpenOffice.
Well, i switched from Open Office not just because I'm a Microsoft fanboy but also because when you have a mobile phone, even an iPhone, you really want to have Outlook for synchronisation purposes.
Oh, and now that I made you read about why I bought it, you can decide for yourself using this link.
You can change the country in the top right corner if you're not from the US, hope it's of some use for some.
