1. A powered, hand held, electromechanical surgical device, comprising: a handle assembly including: a handle housing defining a longitudinal axis, the handle housing including a first connecting feature and a second connecting feature;a circuit board disposed within the handle housing;a battery disposed within the handle housing and being in electrical communication with the circuit board;at least one electrical contact associated with the first connecting feature of the handle housing and being in electrical communication with the circuit board and battery;at least one electrical contact associated with the second connecting feature of the handle housing and being in electrical communication with the circuit board and battery; andat least one first button for actuation by a finger of a user, each firing button being in electrical communication with the circuit board; anda drive unit assembly removably and selectively connectable to a selected one of the first connecting feature and the second connecting feature of the handle assembly, the drive unit assembly including: a drive unit housing defining a longitudinal axis, the drive unit housing including a connecting feature configured and adapted to mate with a selected one of the first connecting feature and the second connecting feature of the handle assembly;a motor disposed within the drive unit housing;a drive shaft rotatably supported in and extending from the drive unit housing, the drive shaft being driven by the motor; andat least one electrical contact associated with the connecting feature of the drive unit housing and being in electrical communication with the motor;wherein, when the drive unit assembly is connected to the first connecting feature of the handle assembly: an electrical contact associated with the connecting feature of the drive unit housing electrically interfaces with an electrical contact of the first connecting feature of the handle housing; andthe longitudinal axis of the drive unit assembly is parallel relative to the longitudinal axis of the handle housing; andwherein, when the drive unit assembly is connected to the second connecting feature of the handle assembly: an electrical contact associated with the connecting feature of the drive unit housing electrically interfaces with an electrical contact of the second connecting feature of the handle housing; andthe longitudinal axis of the drive unit assembly is angled relative to the longitudinal axis of the handle housing. 2. The surgical device according to claim 1, wherein the handle assembly includes at least one second button for actuation by a thumb of the user. 3. The surgical device according to claim 1, wherein the drive unit assembly includes a plurality of drive shafts rotatably supported in and extending from the drive unit housing, wherein each drive shaft is driven by the motor. 4. The surgical device according to claim 1, wherein the first connecting feature is located at a longitudinally distal-most surface of the handle housing. 5. The surgical device according to claim 4, wherein the second connecting feature is located on a lateral side surface of the handle housing. 6. The surgical device according to claim 1, wherein the handle assembly includes an attachment feature associated with each of the first connecting feature and the second connecting feature, and the drive unit assembly includes an attachment feature configured for selective connection to a selected one of the attachment features of the handle assembly. 7. The surgical device according to claim 6, wherein each attachment feature of the handle assembly comprises a recess formed in a surface of the handle assembly. 8. The surgical device according to claim 7, wherein the attachment feature of the drive unit assembly includes a latch assembly configured for selective receipt in a selected recess of the handle assembly. 9. The surgical device according to 1, wherein the handle assembly and the drive unit assembly are in wireless communication with one another. 10. A method of configuring a powered, hand held, electromechanical surgical device, the method comprising the steps of: providing a handle assembly including: a handle housing defining a longitudinal axis, the handle housing including a first connecting feature and a second connecting feature;a circuit board disposed within the handle housing;a battery disposed within the handle housing and being in electrical communication with the circuit board;at least one electrical contact associated with the first connecting feature of the handle housing and being in electrical communication with the circuit board and battery;at least one electrical contact associated with the second connecting feature of the handle housing and being in electrical communication with the circuit board and battery; andat least one first button for actuation by a finger of a user, each firing button being in electrical communication with the circuit board; andproviding a drive unit assembly removably and selectively connectable to a selected one of the first connecting feature and the second connecting feature of the handle assembly, the drive unit assembly including: a drive unit housing defining a longitudinal axis, the drive unit housing including a connecting feature configured and adapted to mate with a selected one of the first connecting feature and the second connecting feature of the handle assembly;a motor disposed within the drive unit housing;a drive shaft rotatably supported in and extending from the drive unit housing, the drive shaft being driven by the motor; andat least one electrical contact associated with the connecting feature of the drive unit housing and being in electrical communication with the motor;connecting the drive unit assembly to the first connecting feature of the handle assembly, wherein the longitudinal axis of the drive unit assembly is parallel relative to the longitudinal axis of the handle housing, when an in-line configuration of the surgical device is desired; andconnecting the drive unit assembly to the second connecting feature of the handle assembly, wherein the longitudinal axis of the drive unit assembly is angled relative to the longitudinal axis of the handle housing, when a pistol-grip configuration of the surgical device is desired. 11. The method according to claim 10, further comprising the step of electrically interfacing an electrical contact associated with the connecting feature of the drive unit housing with an electrical contact of the first connecting feature of the handle housing when the drive unit assembly is connected to the first connecting feature of the handle assembly. 12. The method according to claim 11, further comprising the step of connecting an end effector to the drive shaft of the drive unit assembly. 13. The method according to claim 10, further comprising the step of electrically interfacing an electrical contact associated with the connecting feature of the drive unit housing with an electrical contact of the second connecting feature of the handle housing when the drive unit assembly is connected to the second connecting feature of the handle assembly. 14. The method according to claim 11, further comprising the steps of: connecting an adapter to the drive shaft of the drive unit assembly; andconnecting an end effector to the adapter;wherein the adapter transmits a rotative force from the drive shaft of the motor to the end effector. 15. The method according to claim 10, wherein the handle assembly and the drive unit assembly are in wireless communication with one another.
