mobile devices, is there something beyond the display?

technology today offers several options to carry on your digital life. Devices such as mobile phones, tablets, netbooks and laptops offers a portability solution that suit to any need. however, do we need all of these devices?? or do we need only one that can unify all these?


my question goes attached with somebody concern for the new android tablets, arguing that the applications are not specific for tablet, even more they are the same applications for the mobile, but in a bigger display. but, based on this statement new questions arise: do we need apps for mobile and apps for tablets?.  furthermore, should they be different? or just look better in a bigger screen?

Despite that I'm not a Mac enthusiast, I've found a clue with them, acknowledging their influence in the IT market, in the latest Ipad, which besides of its updated twice faster processor, offers as big development with a choir on the background singing the hallelujah (ok, maybe I might be exaggerating a little) the retina display, which after was adopted in the new mac book (choirs singing at the max volume). So, in the raise of computer power all the companies are following Moore's law, therefore a new, improved and powerful processor is not the wow factor as it use to be, so what is now this factor that will move the people to the stores and buy your product? the apple bid was for a better display.

Now, on the other side, the google side, this company is investing in the "Google glass", which allows you to have everything at the glance of your eyes (see a demo in http://youtu.be/9c6W4CCU9M4). This project reminds me the famous "sixth sense" presented in TED talk (http://youtu.be/fQEHtvNsfKE), which promise that with a single device connected to the internet you can have access to a machine, allowing to carry on the basic task of your digital life.

finally, one more video about how display is the way, is "A day made of glass" (http://youtu.be/6Cf7IL_eZ38) showing how everything will be displayed on "intelligent" glass screens regardless the device used because its amazing compatibility. which brings again to the table do we need different apps for mobiles and tablets?  

So why we need so many devices?,we have  mobiles, tablets (new warfiled will be the 7 inches, besides the 10 inches), laptops, which everyday are slimmer, like a tablet, desktops with bigger screens, as well as devices to share the contents across the house (apple tv, google box). With the time we will realise  that the device won't be important for the user, and what we matter is about portability and mostly a good portable display, unifying all these devices in one. which one will win the war, only the time can say.
