Apple's iPad tablets remain the slate to beat three years after the first model was introduced and the likelihood is, the upcoming iPad 5 and iPad Mini 2 will romp their way to the top with hardly a serious competition.

A new report pointed to the 9.7-inch iPad and the 7.9-inch iPad Mini as the tablets of choice for majority of consumers, not only in the United States but also in the homebase of Apple's closest rival, Samsung.

The two iPads, according to Apple Insider citing reports from South Korea, are the popular among the Korean tablet users. And this has been the case in the last three consecutive years, notwithstanding the gradual gains posted by Samsung's Galaxy Note and Galaxy Tab series in past few quarters.

In the later part of 2013, the two tech titans will tussle anew along with other players, but it is almost certain that iPad will be the clear winner, and here are the reasons why its success will be sustained in the months and quarters ahead.

iPad 5 and iPad Mini 2 is backed by solid tablet ecosystem

There are tablets out there that easily overwhelm Apple's two slates in terms of power specs. The iPad Mini, in fact, is overwhelmed by the likes of Nexus 7 and earlier this year by the Galaxy Note 8.0. Yet the Mini maintained its lead over the other brands, while the Note 8.0 failed to register a giant surge since its release, despite flashing the better capabilities.

What counts the most for the iPad Mini, the new report said, is an ecosystem that delivers a wide option for tablet users, prompting them to overlook some of the Mini shortfalls cited by experts. Both the iPad 5 and the iPad Mini are popular because "rich iPad-only apps (showed) maturity and high product quality," the report said.

Apple devices flex better quality

Apple builds its products with a straightforward approach. The design is simple but elegant, therefore attractive to millions of buyers. The technology that powers the iPads and iPhones deliver innovation, which translates to quality features, according to analysts.

This Apple strength was again in glorious display when Samsung issued its Galaxy S4, wrapped in exciting feature that propelled the Android flagship to 10 million buys in mere four weeks. But the attention-grabbing GS4 features were soon deemed by experts as lacking the practical purpose. GS4 users will eventually forget these new features once the novelty melted away.

The same is not true with Apple devices, both for the iPhone and iPad. To date, all the features that Apple engineers packed with the gadgets are aiding consumers to achieve better productivity while providing equal amounts of amusement, analysts argued.

Apple re-innovates with the iOS 7 on iPads and iPhones

Simple, less clutter and high usability are the guiding principles in the high-profile redesign of the iOS 7, which will power all the gizmos that Apple will unleash beginning September 2012.

The core aim in bettering the iOS platform, according to Apple CEO Tim Cook is to inspire loyalty among Apple device users, prodding to stay within the system and opt for the next iPhone and iPad models when upgrade moments come. Also, Apple is well aware that consumers highly satisfied with the ecosystem surrounding iOS devices will lead to higher revenue generation.
