Wow, first to review, well i bought this software becuase i tried it first and it is pretty decent, i liked the new features of 3D, pixelrender, the new text engine, and the new drawing api. these are the big differences from adobe flash cs3, which i used at college due to me not seeing the need for it at home, but i started wanting to make flash websites, and since cs4 had just come out i decided to try and then buy.
the actual software; this software is for making most things related to flash apllications, especially due to the rights being owned by adobe, and adobe being the actual creators of flash.
you can use this program to make a website with animation, animation, and multiple of things.
3d: this is a really good new tool especially if you want to make something rotate that looks a little like a globe, this is a real cool feature especially if you want to make something like that, it includes many more features like this just so you can make your project perfect
