Wrong. I use the two finger zoom all the time in Outlook 2013. And yes, they haven't released the metro version of Outlook yet. That will be a free upgrade for existing Office 2013 users.
Great point, thanks a lot.
This is definitely a valid answer to my question but unfortunately still not applicable to me, since I don't want to pay for a huge software suite to fulfill the purpose of any other, even the simplest freeware product.
Maybe I'll give the appstore a chance - not too optimistic.
