Before you folks rage...I own an iPad.
1)I love how this survey considers an iPad a mobile PC...but not an iPod Touch or an iPhone?...
2)And that an iPad is missing so many qualities of a laptop/netbook (camera, normal storage capacities, USB and other industry standard ports, ability to save files (other than picture, iTunes movies, and mp3s) on the unit, etc)...so the iPad really doesn't even compare to a traditional personal computer.
Surveys like this are useless. The iPad is a lovely device...and certainly not for everyone (example: people who already own an iPod Touch and/or iPhone and/or numerous traditional laptops). But to claim that Apple is in 3rd place worldwide because the survey is lumping an iPad into the mix is an injustice...the whole point of an iPad is that in its advertising and Jobs' speeches the iPad is NOT a traditional laptop/netbook.
What's next...comparing LCD monitors to printers?
