It's not good news for Google, etc. as their Swiss employees just got 15% more expensive.
Additionally every large company does currency hedging to protect itself from those events.
Nothing changed for my Swiss colleagues who don't shop in Euros.

More of my experiences within Switzerland you'll find in here: "Eight reasons why I moved to Switzerland to work in IT" http://goo.gl/EIX4UX (Full disclosure: If you're from the EU and looking for a tech-job over here, I'd be happy to help out).
Prices of foreign goods in Switzerland should slowly converge to the lower lever.
If I were doing so I would hate myself for not keeping as much as possible in CHF and just converting today for a 15% more EUR.
now I just need to decide if I should keep them or convert to EUR and close the account :D
