Which are the Apple devices you couldn't live without?
The iPhone is definitely very popular... and no Apple laptop so far!
I can't live without a general purpose computer so the MBP serves that need. I tend to use my iPad more than my iPhone due to the larger screen. The only time I'm dependent on my iPhone is when I need to travel light and don't want the iPad with me. Otherwise I could do ok with a feature phone.
Gotta have my iPhone for my social life, iPad for school work and fun.
MacBook Air for dj'ing
And 27" iMac for music production
