So you just upgraded to Lion, or brought home a new Mac with Lion pre-installed, and you’re overwhelmed with excitement. You booted it up for the first time, and you slowly opened all of the new versions of your favorite apps to see how they work in Lion. When you finally got to iCal, you discovered that Apple’s new iCal themes looks like your grandpa’s Filofax. Then you opened Address Book only to be greeted by a first edition Dickens novel.
Much to our collective dismay, Apple wrapped both iCal and Address Book in faux leather motifs, complete with paper shreds at the top of your calendar and a faux bookmark at the top of your Address Book. If you have not had the chance to see it, this is what is awaiting you when you fire up iCal in Lion.
