You NEVER know when you're going to need a floppy drive. I keep a USB Floppy drive in my pocket at all times!
/sarcasm
It's a humorous mock-up to try and quell the trolls who keep saying "tah macbuk air iz teh suxorz!" and give everyone a good laugh. I enjoyed it! (first 10 times....)
Still not good enough for me. If it doesn't have a built in 8 track player for my music and a beta player for my movies then Apple will NEVER get my money!
