After releases of Apple phone, Prada phone, and whole bunch of diamond/ gold phones, it seems like every brand needs ther own mobile extention these days. Branded cellphones is the new thing and people buy it since they trust these brands. You can't imagine something will be wrong with the new iphone, just because you had a great experience with company's ipod, but in fact Apple has zero experience in the mobile world. Our brains have a weird trust mechanism, and when we buy a phone from Prada for $800 we are not nessesarily thinking wheather it has Bluetooth or not, we buy it because it's Prada.
The next brand to jump on the trend is Porsche (which by the way makes more sense than Prada somehow). They just presented their new Porsche P'9521 mobile phone this week. I can't imagine the pricing on this sleek super tiny phone, but I'm sure Porsche lovers will have to shell some big bucks this time as well.
