Probably not a short term investment. By the article, $11 billion total (including the recent $4 billion announcement) from 1996 - 2012. Let's take away the recently announced funds and we have $7 billion spent from 1996 - 2012. My educated guess is the fastest burn rate is about 4-5 years to spend the $4 billion.
Why this is repost of old news? This was announced by samsung back in August (below is link), also here on EET.
It's nice to see Korea investing, once again, in the USA. Meanwhile, Apple is moving it's business to TSMC (China). Can it be that Samsung's tablets and phones are more "American" than Apple tablets and phones?
