The discussion in this thread can be improved by clearing up a huge misconception: that one needs super high apm to either enjoy or be good a RTS.
Let's take the best RTS ever made for an example: Starcraft Broodwar. You see Pro Gamers with 300 to 400 apm in tournaments and stuff, but this number does consist of many bullshit clicks that do nothing (like clicking on the same space on the ground 3 or 4 times just to make a unit move for example). I mean, Pro Gamers can multi-task very well and their "real" apm (actual meaningful clicks) is higher than that of other players, but this doesn't matter for the average guy trying to enjoy these games.
The truth is, with much lower APM like 80 to 180 (which anybody can do) you can have fun and be good at the game.
Strategy, experience, thorough understanding of all the units, their strengths and weaknesses, AND a certain amount of creativity in your playstyle is MUCH MORE important to become good and have fun, because moving units, attacking with units and bulding units in a fairly fast and efficient way is something anyone can learn quite easily.
