One of the reasons for MS being able to extract such amounts (same as their whole OS lic costs) from HW manufactures like HTC & Samsung is the continuing almost monopoly of MS Windows as a desktop OS in business environments. And – as said - MS Windows only supports MS patented file systems directly (fat, fat32, NTFS). So as a HW manufacturer if you take the simple route you use one of those fs on your devices. That's how this story is told reg FAT patents. Samsung, HTC e.a. how about writing a Windows driver & Front-end app (e.g. similar to the Nokia or Blackberry desktop apps) that can read a non MS patented file system from your devices – would that not be much cheaper or is their more to this story?
