I drink filtered tap water at home but when I'm out the only real choice is bottled water. I always thought this debate was somewhat irrelevant since a thirsty person on the go is probably going to buy _something_ to drink. If it's water, soda, fruit juice, tea, etc it doesn't really matter. If you buy bottled water to drink at home a filter would be a very good investment.
