Is credit necessary and how/where do you bank?
noodle: credit is necessary if you have plans to ever get anything with a loan, such as a car or house or, as you say, entrepreneurial purposes.  people won't give you money if you don't have a history of being responsible enough to pay it off.  its also good to have a line of credit for emergencies.get a card, use it to buy small things on occasion, and pay it off in full every month.edit:
oh, also, i bank with bank of america and hsbc.  hsbc for the high yield online savings and payment accounts, bank of america for the size, checking, and potential perks coming from establishing a long line of credit with a big bank
