another day another Adobe security fail
You don't have to be a mactard (which I am not) to hate adobe software. Bloated, buggy and worse of all the least secure software in the industry (even M$ has finally wised up some unlike 400 days in the wild Adobe). Probably the single biggest security threat on your computer right now is flash or some other piece of Adobe floatsam (at least chrome comes with it auto bundled and auto sandboxed now). Having no viable alternative to flash (that is any other software that will properly render flash 8+) is the single biggest threat to the web. Even pdfs are less of a threat with a viable alternative such as Foxit Pro.
