Regarding that hardware-keyboard it's supposed to exist at one point. At least from the technical possibility citing Dillon on techcrunch: “Of course we will be offering a choice of Other Halves for the user to buy but this is a place where we want to see others get involved. Designers can design Other Halves for the device, engineers or hackers or techies can design new interfaces and maybe add physical hardware features that they wish they had on their device but might have a smaller market than to deserve having a whole entire device,” http://techcrunch.com/2013/05/20/jollas-other-half/
