I'm not sure I agree. Most people will still be using Office 2000/XP and some even older versions, and upgrading costs hundreds of dollars (or more!). All the other mail clients, however, you can download and use today at no cost.
Also, I only had Office XP at hand when writing the review, which only helps to better illustrates my point I think.
