Not Buildings If you go to see Silicon Valley, what you'll see are buildings. But it's the people that make it Silicon Valley, not the buildings. I read occasionally about attempts to set up "technology parks" in other places, as if the active ingredient of Silicon Valley were the office space. An article about Sophia Antipolis bragged that companies there included Cisco, Compaq, IBM, NCR, and Nortel. Don't the French realize these aren't startups? Building office buildings for technology companies won't get you a silicon valley, because the key stage in the life of a startup happens before they want that kind of space. The key stage is when they're three guys operating out of an apartment. Wherever the startup is when it gets funded, it will stay. The defining quality of Silicon Valley is not that Intel or Apple or Google have offices there, but that they were started there

Tarbimise kontekst kõige levinum vabadusest rääkimise viis. Vabadus ei ole kõigile ühesugune. Vabadus vajab tarbekaupu, et ennast manifesteerida. Ebakindluse kasv - vrd prognoosid tuleviku suhtes. Mobiiltelefon oluline vabaduse sümbol. Vabadus piirangutest, iseteadvus. 2003 aastal 65-75% mobiilid. Nortel 20-29 94%, vanadel 65-74 27%. 1999 aastal üks kolmest enamreklaamitud tootest.
