I have downloaded the Office Professional pack, and I like it, the new redesigned user interface takes a little bit of getting used to in Word, but Outlook looks good with new looking calender etc. I haven't tried, publisher, excel, powerpoint and there is something called Infopath which I have no idea about.
It appears that Microsoft have actually done something good for a change, but I want to try this for a couple of months to give it a thorough testing. Also it looks like the whole reviewing and altering of documents has been improved tenfold....
