If the greedy Wall Street analysts and the fat cats from the big banks are willing to follow your suggestion of "try, try again" to give ST time and money, I'll buy you a ticket from anywhere in the world to Switzerland and pay you for a 5-day decent hotel accommodation.
ST-E has much better fundamental core strength than the laughing stock like Renesas Mobile. For this to survive and to prove its might, persistent investment are needed. STM doesn't seem to have the cash. The investment community in Europe has unfortunately been following their greedy counterparts from Wall Streets and is unlikely to put up with the investment. So, the best course is to find a good home for the STE. STM should look east for the takers - Korea or China!
ST-Ericsson cannot survive against Qualcomm (high end) and Mediatek (low end). They should stop but splitting analog and digital units will not help. Their advantages in the sensor area will decrease as many other suppliers are active in this market.
