nah, don't like it .....unnecessary.

The only odd exception I make is for Italians, or people with Italian parents who've probably heard Italian words and names pronounced with the accent their whole life, and saying "Campagnolo" with a U.S. or Aussie accent may sound strange (or "foreign"?) to them.

It's just like someone odering a cappuccino and a latte with an Italian accent -- there's no point.
It's not as if the words "cappuccino", "latte" or "Campagnolo" will be misunderstood in the U.S. if they're spoken with a U.S. accent.

This is actually a pet peeve of mine.

I often hear people using the "sexy" western European accents, but I never hear anyone using a strong Chinese accent to order Chinese food, and I've never heard anyone use an Indian accent to read out the names of an Indian cricket team!! I wonder why that it is? Oh yeah, because those accents are considered "trendy"...
