Going with a bank that has the highest rate isn't always good advice though. For example, a month ago I tried to setup an account with UFB Direct. At the time it was a highly rated bank on most of the websites that review high yield savings accounts. First I filled out the application. They responded 2-3 days later asking for additional information. I sent them the additional info, and my account was created several days later (about a week overall to create the account.) Then I wasn't able to transfer money from my other account to fund the UFB account. I contacted customer service, and 3-4 days later they responded with information that didn't help. After a few weeks I finally gave up, and asked them to close my empty account. I won't put my money into a bank where customer supports takes several days to respond.
Then the Apple's savings account came along. I decided to try it while I figured out what to do with my money. It literally took me 3 minutes to create the account, and transfer all of my idle cash into it. So yeah, maybe I'll move my money later into an even high rate account. However, the Apple savings account is so easy to use that I may keep my money there.
