Is it?  This has more than likey been a subject matter here at Lime.  I wish that it were a staple though.  I have been raised to distrust them, even though other family members and every other person I come in contact with has one. People infact find it strange if your kitchen is without one! I recently read that they are no more dangerous than a television or a computer! Not to be overused or abused. So many health food products even have micrwaveable instructions.  Should I just do without one as I have been or when the next oppurtunity arraises get one?

When in a new environment, there isn't really a better way to get the lay of the land and see the sites than walking. When you're walking through a city you see many of the more subtle things around you that you miss when in a car or even public transportation. Reducing pollution AND experiencing a new city more completely? Yes please.
