Google, Yahoo & Apple

These three and other large, well-capitalized tech companies are buying large tracts of land in Silicon Valley for future expansion. This is a great sign for the long term health of the Valley. With large investments, these companies will be more apt to stay than ship off their workforce to cheaper locales such as Austin. That was a boondoggle that Apple went through in the mid 1990s. Many dissappointed Apple families moved back to the Bay Area only to find a costlier transition. Silicon Valley is here to stay. That's why most tech giants are betting long.
