9. The protective case of claim 1 wherein the external electrical interface of the electronic device is accessible when the electronic device is installed in the protective case, the attachment mechanism further configured to enable the attached accessory to interface to the external electrical interface of the installed electronic device when the accessory is attached to the protective case.
10. The protective case of claim 1 further comprising a button pad for actuating a button of the installed electronic device from an outer surface of the protective case.
11. The protective case of claim 10 wherein a side of the outer shell includes a cutout area in which a portion of the inner liner extends to an outer surface of the outer shell, and wherein the button pad is formed in the portion of the inner liner in the cutout area.
12. The protective case of claim 1 further comprising a third aperture in a side of the protective case for accessing a switch of the installed electronic device.
13. A protective cover for use with an electronic device having a touchscreen interface, a camera, and an external electrical interface, the protective cover comprising:
a shell configured for receiving the electronic device and at least partially covering a housing of the electronic device, the shell including:
a first aperture configured to permit access to the touchscreen interface of the electronic device when the electronic device is installed in the protective cover;
a second aperture configured to permit optical access to the camera of the installed electronic device; and
an attachment mechanism configured for attaching an accessory to the protective cover, wherein one of the attachment mechanism of the protective cover and the accessory includes a receiver configured to slidably receive a rail member of the other of the attachment mechanism of the protective cover and the accessory to removably attach the accessory to the protective cover, and wherein the attachment mechanism of the protective cover further includes a snap feature configured to engage a corresponding snap feature of the accessory to keep the accessory removably secured to the protective cover.
14. The protective cover of claim 13 wherein the snap feature of the protective cover includes one of a ridge and a groove and the corresponding snap feature of the accessory includes the other of the ridge and groove.
15. The protective cover of claim 13 wherein the snap feature of the protective cover includes one of a protrusion and a detent and the corresponding snap feature of the accessory includes the other of the protrusion and the detent.
16. The protective cover of claim 13 wherein the receiver includes a channel for receiving the rail member, the channel having a cross sectional size at a first end of the channel that differs from a cross sectional size of the channel at a second end.
17. A protective cover system for use with an electronic device having a touchscreen interface, a camera, and an external electrical interface, the protective cover system comprising:
an accessory for use with the electronic device; and
a shell configured for receiving the electronic device and at least partially covering a housing of the electronic device, the shell including:
a first aperture configured to permit access to the touchscreen interface of the electronic device when the electronic device is installed in the protective cover;
a second aperture configured to permit optical access to the camera of the installed electronic device; and
an attachment mechanism configured for attaching the accessory to the protective cover, wherein one of the attachment mechanism of the protective cover and the accessory includes a receiver configured to slidably receive a rail member of the other of the attachment mechanism of the protective cover and the accessory to removably attach the accessory to the protective cover, and wherein the attachment mechanism of the protective cover further includes a snap feature configured to engage a corresponding snap feature of the accessory to keep the accessory removably secured to the protective cover.
18. The protective cover system of claim 17 wherein the receiver comprises a dovetail slot.
