Sour grapes: a good reason; just not a true reason.Flash, talk about a piece of poorly optimized software. There is a reason it has become nearly obsolete. You only need all that cpu power to browse the web when you try to run crap software like that.
Flash is still rather common on the internet (http://w3techs.com/technologies/details/cp-flash/all/all) and is hardly obsolete. It does run poorly on the iPad largely because it is sadly underpowered relative to real computers, laptops and tablets like the surface which can "easily" handle Flash.
