Let's be fair, you say they took a step forward with multitasking.... It only took them 4 generations to do so. BlackBerrys have been doing this before the original iPhone was released.
You make a good point, but with BlackBerry Messenger, you can BBM any BlackBerry, regardless of model (legacy or not), regardless or carrier, etc as well as over carrier network or WiFi. For the FaceTime app, you can only chat over WiFi (not carrier network) and only to other iPhone 4 users.
The difference between stupidity and genius is that genius has its limits.
When you take things for granted, the things you are granted, get taken.
Even a mosquito doesn't get a pat on the back until it starts to work.
Too many people miss the silver lining because they're expecting gold.
