Is this a joke? I bought a 6 inch cable (USB/30-pin) for my iPhone by accident once and it's a complete waste. No practicality at all
I use a 6" on my MBA to sync my phone and iPad at my desk. Lays flat beside the device and does the job without extra clutter on my desktop. I carry 6-inchers in the slim pockets on my iPad and MBA cases so when traveling I can transfer pics to/from devices for editing before sending or just for backup storage on long trips.
I don't object to those challenging the price, though some seem obsessive about calculating what should be the "true" price.
I do find it funny/odd that so many seem so sure of their own ability-or right-to decide what might offer practical uses for others. Those people seem very full of themselves. I don't think they'd make very good friends, telling me with absolute certainty what I should want for breakfast or what I should want to wear.
I'm just sayin'
