Not an entirely accurate review.
Quote: "The current day is always the largest and the other days go from left to right (even though for some reason my eyes keep wanting to go from top to bottom)" (pertaining to PI's Week View)
PI allows you to arrange days in Week View top-to-bottom style. You can also select the size for the current day (so it can be the same size as the rest). You can select to always have the week start with current day, or have an "actual" week view starting with Monday, Sunday or whatever you choose. So Matt's statements regarding PI in this area are quite false. It's actually very customizable and this is also one of the reasons I myself prefer PI.
