I find Ming-Chi Kuo's supposed report, quite sketchy for these simple reasons:
- Technically like one of the users "Mystic Frost" pointed out on another thread, the next step in resolution is 3072x2304 with a scaling of 3 from 1024x768 (for app compatibility). That would first of all place it at essentially at 50% of more pixels straight away. 40% indicates a change in resolution or even a slight size change.
- Secondly for a company claiming that Retina display is the more or less the optimum display for the average joe, I really wouldn't think they would really try to kick up the display ( not possible to standardize it at 326 without changing resolution).
-Battery life is always been the concern, even now there is considerable doubt about whether Apple will be able to maintain battery life of 10 hours, with such a thin enclosure and battery. I think they should work on improving the battery life instead of kicking up the resolution.
Kuo has been fairly accurate ( if you ignore the fact that he keeps updating his report every few weeks citing things like pressure from competitors, sudden change of plans, sudden breakthroughs in technology, etc.) He started by claiming last year itself that ipad 5 would launch in Spring, then it became late spring, then summer, then finally moved into autumn, before he said it would launch in last quarter.
I say read his reports with some caution.
