Yummy! It seems denser than before, but I'm not an expert at testing or seeing little differences. It certainly runs my apps faster!
Here's a pic. Apparently, the iMac camera takes a mirror image picture (like the left). You can't read the text! If I turn on effects "mirror" it will add in the image at the right, so things look a little normal. (never used my iMac's camera before)
Pic shows the "folderizing" in iOS 4, too. The two black images with little
blocks inside them. I love this new capability!
