I've had only the best experiences with the non-U.S. support lines. I've found that the people on the other end often spoke better English than me. In fact, I could understand them much better than most people I've talked to from the deep south or highly urban areas (regardless of skin color). Plus, the ones I've talked to seemed to be more patient than their American counterparts and they're willing to gab about where they're from and what time it is there and whether or not they eat dog and so on. Perhaps I got lucky and talked to some of the good ones?
Speaking from a capitalist perspective (though not really along the subject lines of this thread), more power to the corporation that can find a willing and able labor-force outside of the U.S. borders. If it costs them less, it'll cost you and me less.
Think about it- if a company like Dell finds that it's cheaper to run phone lines half-way around the world and set up all the infrastructure overseas for something that probably could easily be operated stateside, there's got to be a good reason (Lazy Americans? Nooo... couldn't be.
).
If you don't like it, you don't have to "go to Dell." Like what Manic_Skafe implied, you have the freedom to buy from whomever you want. Vote with your wallet/purse.
