I meant to say 100 million but the number got dropped between keyboard and chair, sorry ;-).<p>Best estimate is that there are around 200 million laptops a year sold (2014) based on a PC market of over 300 million and that laptops outsell desktops (worldwide).<p>Looks to me like tablets sell roughly at the same rate, around 230 million units.  (I think it&#x27;s not easy to find comparable numbers so maybe my data is off).<p>So given apples approximately 25%-33% market share of tablets that&#x27;s just around 50-80 million ipads, which is still well below the top three in laptop sales (100 million).
