I also like to re-read one of my favorite books "Why business people speak like idiots".
The title of the book is a bit harsh, but like the link below, they just highlight clarity and common sense when communicating in the work place.

Here's a brief screencast that I did going through some of the basic features of the newest Ubuntu release (Natty Narwal).
Overall, I feel that this is the most accessible linux distribution for the Mac and Windows set. It comes bundled with a great productivity suite that is compatible with the MS Office suite, offering enough functionality for all but the most discerning Office power user. Evolution e-mail is the equivalent to MS Outlook, and other than the somewhat spartan look, it offers up a majority of Outlooks features. I like my Outlook add-ins (like Evernote), but probably not a big deal for most users if your looking for a highly functional mail client. Here's a link to a bit more info regarding LibreOffice.
Ubuntu also integrates socially with an excellent chat client (Empathy) as well as a social broadcasting client for Twitter. In particular, I like the notification system employed by Ubuntu. I find it to be a more elegant solution than many of the Windows clients.
The aspect of this latest release that seems to be the most divisive is the Unity user interface. Mac and Windows users will feel right at home using this, although a quick search through any of the forums will show that it is either loved or hated.
Overall, if you are looking to give something new a try, or you are looking to extend your hardware's lifecycle a bit, give Ubuntu a shot. It's easy to install, fairly lightweight, boots quickly, and offers a robust set of features. The only (minor) downside is that while there are access to many great programs (free and paid), if you really need to run a Windows program, there is some extra effort required. When my windows 7 laptop draws near the end of it's lifecycle, I plan on installing Ubuntu and giving it to my Mother, who has been using an Ubuntu netbook that I built for her for a few years.
