ABSTRACT:
In another aspect, a handheld electronic device is disclosed that includes a body sized and shaped for holding by one hand of a user. The device further includes a user interface comprising a plurality of buttons for operating the device and at least one securing element coupled to the body. The securing element is adapted for engagement with at least one digit of the user's hand to facilitate holding the device so as to allow the user to operate the device, via its user interface, with one or more other digits of that same hand. In some embodiments, the device can be utilized for calculating a variable value associated with a loan (e.g., monthly payment) based on entered values of the other variables of the loan (e.g., amount, interest rate, and duration).
