With the advent of iPhone and Leopard CALayer - or whole layer trees - often get used in favor of NSViews. The CALayer and its subclasses offer many convenient ways of getting data displayed quickly and - since we all like eye candy - with subtle and less subtle animations. Blending in or out datasets of a complex graph using a fade effect for free is just nice.

After getting into the way layers are hosted, drawn and animated, I had all the tools to write classes for graphs like I never was able before. Or not that easily at least. I need a print out. ... ... which was easy to get from a NSView. Not so easy from a view hosting (in any kind) layers.

So, in context to one of the other posts here - once again a new cat. I already had a lot of experience due to available developer seeds and have now switched all my Macs to 10.6. So far I am happy, my own apps as well as all the apps I am using on a regular basis are working just as expected. What I like most is that I finally can switch all my developing to Xcode 3.2 and make built-in use of CLANG. More on that in a couple of days. In short - it is nice to have it in the development environment without the need to run terminal commands and such.
