    "1. Display device including a display and a hardware power button, wherein the power button is operable to open from the device to receive a subscriber identity module (SIM) card, and wherein the power button is operable to close so as to store the SIM card in the device, wherein the device is operable to use the SIM card to define a SIM identity for the device. 2. Device of claim 1 wherein the display includes a touch screen. 3. Device of claim 1, wherein the power button is openable by operating a soft key in a user interface of the device. 4. Device of claim 1, wherein upon operating the soft key, the power button opens at least 2 mm. 5. Device of claim 1, wherein the device comprises front and back major faces, the front major face arranged to present a first display screen and the back major face arranged to present a second display screen different to the first display screen. 6. Device of claim 5, wherein the second display screen is a bi-stable display screen. 7. Device of claim 6, wherein the bi-stable display screen is an E-ink bi-stable display screen. 8. Device of claim 6, wherein the bi-stable screen occupies greater than 70% of the area of the major face of the device on which it is located. 9. Device of claim 1, wherein the device is portable. 10. Device of claim 1, wherein the device is a mobile phone, a portable digital assistant, a laptop, a digital audio player (eg. ipod), or a tablet computer (eg. ipad). 11. Device of claim 1, wherein the device includes a concave front face and a convex rear face. 12. Device of claim 1, wherein the device includes a card receiver assembly including a Shape Memory Alloy component, wherein the assembly is operable to receive the SIM card, and wherein the Shape Memory Alloy (SMA) component is actuatable to release the SIM card from the assembly. 13. Device of claim 12, wherein the Shape Memory Alloy component includes a wire. 14. Device of claim 12, wherein the Shape Memory Alloy component includes a bundle of wires. 15. Device of claim 12, wherein the Shape Memory Alloy component is actuatable by passing a current through it. 16. Device of claim 15, wherein the actuation voltage applied to the component is reduced to achieve an increased number of actuations. 17. Device of claim 12, wherein the Shape Memory Alloy component is actuatable using an energy of between 0.1 J and 4 J. 18. Device of claim 17, wherein the Shape Memory Alloy component is actuatable using an energy of between 1 J and 4 J. 19. Device of claim 8 wherein the assembly includes a hook operable using the Shape Memory Alloy component to hold the SIM card in place, and releasable using the Shape Memory Alloy component to release the SIM card from the assembly. 20. Device of claim 12, wherein the Shape Memory Alloy is a two-way shape-memory. 21. Device of claim 12, wherein the Shape Memory Alloy is copper-aluminium-nickel or nickel-titanium. 22. Device of claim 12 wherein the device comprises a computer. 23. Device of claim 22, wherein the Shape Memory Alloy (SMA) component is actuatable by the computer. 24. Device of claim 22, wherein the Shape Memory Alloy (SMA) component is actuatable by software running on the computer. 25. Device of claim 24 including a user interface, wherein the Shape Memory Alloy (SMA) component is actuatable by a user interface instruction received by the software running on the computer. 26. Device of claim 1, wherein the device includes a SIM card receiver comprising a hinge door mechanism that prevents release of the SIM card in response to a pressing of the power button, but allows contact to a standard power tact switch. 27. Device of claim 1, wherein the SIM card is a mini-SIM, a micro-SIM, or a nano-SIM. 28. Method of releasing a SIM card from a display device comprising a user interface, a display, a computer, and a SIM card receiver assembly, wherein the assembly is operable to receive a SIM card, the method comprising the steps of: (i) the computer receiving an instruction via the user interface to release the SIM card from the device, and (ii) the computer actuating the SIM card receiver assembly to release the card from the assembly. 29. Computer program product, the computer program product executable on a display device comprising a user interface, a display, a computer, and a SIM card receiver assembly, wherein the assembly is operable to receive a SIM card, the computer program product when running on the computer operable to perform the method steps of: (i) receiving an instruction via the user interface to release the SIM card from the device, and (ii) actuating the SIM card receiver assembly to release the card from the assembly."

  "description_excerpt": "1. Field of the Invention\n\nThe field of the invention relates to display devices including a display and a hardware power button, especially to display devices for receiving a subscriber identity module (SIM) card. The field of the invention further relates to methods and to computer program products associated with such devices.\n\n2. Technical Background\n\nMany portable devices include assemblies which can receive cards which enable or enhance device capabilities. For example, mobile phones include SIM cards, and digital cameras may include memory expansion cards such as SD cards.\n\nHowever, such devices may be stolen, and the stolen device may be used by an illegitimate user after changing a card, because the card may contain information which prevents another user using the device legitimately. It would be desirable to have a way of preventing a stolen device from having its card replaced without first being subject to a power on and potentially to a password entry process, which could help to ensure that only a legitimate user of the device can change a card of the device, even though an illegitimate user could still make a drastic step such as partly dismantling the device to access the card. Making it very difficult to change a card illegitimately may be particularly important when the device is relatively expensive, such as a smartphone, such as one described in WO2012044201(A2), which is incorporated by reference, because expensive devices are attractive to thieves.\n\nReplacing the SIM card in an iPhone 4S is easy. All you need is a SIM card eject tool or a small paper clip.",
