It is exactly the same what is happening to Nokia Networks. What saves them is fact that mobile networks market is pretty much closed and there is very high barrier of entry. If the market would be more open (patents!) - Nokia wouldn't survive a day there. Nokia top management have no clue about technology, they are not engineers so you can sell them any s##t you what if you have smooth talk. Nokia suffers also from politics and internal battles between sites and organizations (basically Finns vs everybody else). This results in ubiquitous NIH syndrome. Nokia Net reinvents wheel all the time, and almost every time they get a square.
