it is not about ARM, it is about phone OS: Android and ApplePhoneOS.
Well, that would be my biggest worry. In recent years, ARM has done a lot of development at the low end of the market: CM3, CM0, CM0+, CM4. It would be bad if that all stopped and they only did development on Phone-class (and higher) chips...
(I'm also an "investor." This purchase looks to cheat me out of my first "ten-banger" (currently up 914% since 2006.)
As for less successful investments, my ST stock is down over 15% in the last year, and Cree isn't doing so well. My MCHP is up about 100%, but that's somewhat less than a NASDAQ index fund would have been over the same period.)
