Will Nokia enter the PC market?

Nokia´s CEO has revealed that they are at least considering that option. This is a proof that the difference between the "mobile world" and the "pc world" gets more and more blurred. A practical aspect of this is that security applications needs to be developed independent of the platform. I see this as an end for all the mobile specialists applications such as simple push technologies. Why not use a proper and secure vpn for access from mobile phones instead of inventing something that only solves the "mobile problem"? We need to treat access from mobile phones the same way as we treat all access...and there is no better way to do that then to use a prober vpn with 2-factor authentication, encrypted and compressed traffic, NAC and granular access. Why inventing another “silo” instead of building on technologies that already work?
