I am so upset because the trackpad on my gorgeous new 15" unibody MacBook Pro is cracked! I was iChating in my bed and a picture frame fell off the shelf from above me and onto the trackpad! The glass cracks much easier than I thought! The machine is still under warranty (30 days) so I'm hoping Apple will fix it when I take it in this week! Unibody MacBook owners beware-- the trackpad is most definitely glass and cracks easily!
