Is mobile device a fashion item?

I read that now bar type cell phone is getting popularity. Once people had jettisoned bar type in favor of folder type. Is it some kind of fashion item? You know fashion designers make money. They make skirt short and long alternately year after year. Maybe cell makes can do the same thing to accelerate the cell phone exchange rate.

Also I read Gucci makes around $180 leather case of pocket PC. Hmm...it might look nice with Gucci logoed cell showing off.
