The iPad is the premier tablet and it’s probably nearly the perfect size and weight for its form factor. That’s not to say that within the form factor there is no room for improvement. A screen that takes up most of the face should be a near term target, as should an auxiliary screen on the back face that provides bright light reading and low power / speed interactivity for those who don’t live indoors all the time. To support the iPad as a companion device, multi level security is a growing need.
Make the bezel the same on the iPad as minimal as possible (get rid of the push button) push the screen out to the edge, don’t change the shell size. This with continued pixel densification will put the screen on another level altogether. Make thumb and palm detection native and intelligent enough to enable me to rest my palm on the screen and write with a stylus as if the screen were regular paper.
Put an eInk reader panel on the back to enable the display of text and graphic art, this will enable high light low power reading applications and some other limited visual bandwidth applications such as phone etc. (This will be accomplished with a smart cover but it would be cool if it were integral with the iPad.)
The radio suite & battery life along with the camera, face time, GPS, and other built in sensors are probably good enough not to call for increases in size weight, but neither should they be decremented.
The iPad is far to big a part of many people’s eLives to leave to the pitiful protection it has today. We need multi level security, enable me to turn the iPad on as if there is no security for consuming web pages, playing games, and using certain apps. But for other functions use face recognition, symbolic coding other than a number pad, voice recognition, retina image recognition and even finger print recognition in combination to protect various levels of data in the unit.
Enable cyber security with one or more over watch processors that is not linked to the outside world for some level of checking to make sure that the tablet has not been compromised. A version of this ‘chip’ may be linked to a secure remote system (short-range) so businesses or organizations can disable certain functions of the iPad remotely to make sure that pictures, audio, or other data cannot be put into memory without authorization. This Big Brother functionality is a bit daunting but at least the over watch processor is probably going to be needed. The full BB may be an external attachment and not integral so one can shed it easily….
