With the huge shift from keyboard to touch in the last few years the iPad, Smartphone and Tablet computer have turned the complex desktop computing metaphor which befuddled most users to the point of only understanding Outlook, Windows and Word into devices grandma and grandpa are actually happy to pick up and communicate with the grand-kids because its easy...
The new era of computing is all about being mobile, devices have 10hr battery life, they are 3G and 4G and designed to be used on the go with the cloud, and free
That is until you want to put the content from your mobile device onto the TV
Now I'm the first to admit that it is possible in a locked in world to use technologies such as Apple Airplay or Google's Chromecast. These are however proprietary systems locked into Apples iDevices are Googles Chrome OS/Browser and don't work at the family gatherings.
Its Christmas and there are photos all the family want to show, the TV is the best place to show them, however that mix of iPhone5, Galaxy S4, Nokia Lumia, Acer Tablet etc which have found there way into the family don't have a single service which can be used to easily display the content from the tablet onto the TV.
This would need to be an open standard, cross platform, easy to implement, and capable of high def resolutions over wireless networks.
That in itself is no mean feat, you'd have to get TV Manufacturer buy in long term, and thats not easy as the DLNA alliance will attest to. Until such a standard becomes just that a standard an intermediate device needs to be plugged into the HDMI port which will support whatever is coming over the airwaves.
Id suggest as the internet of things grows bigger, and we move over to these portable devices as our main computing devices the industry needs to find a cheap, open solution to this problem and stop focusing on the Airplays and Chromecasts or this world..
