I set up a new W7 PC for my parents last month. Checking what they really needed, I deleted the trial version of MS Office, and simply installed a current version of Open Office. They remain delighted with it.
I couldn't use it myself - I've tried, but I use too much of the high end functionality of Word and Excel doing engineering work, but for the vast majority of users, it's more than adequate - and in many ways a bit more user friendly.
