Apart from deciding that Strathclyde University (one of my old haunts) was holding 'a Mobile Conference in England' (it's in Glasgow) and hilariously labelling Symbian OS as 'a small kernel OS maker for mobiles,' Corante understands one key feature of the mobile market. Selling lots of units means you make a lot of money, even if the unit price drops a bit. Put simply, Symbian is a classic representation of Moore's Law.
Glasgow is in England, Symbian is a Kernel Company, Moore's Law Works
