Samsung has officially rolled out the new Galaxy Note tablet and this time around, it is a full-sized slate and in fact a tad larger than iPad with screen size of 10.1 inches.

The new Samsung device, the South Korean tech giant said, will hit for now limited but key markets in the United States and the United Kingdom, and with controlled issues on the company's home turf.

The Associated Press (AP) has reported that for the moment, the Galaxy Note 10.1 will only be made available to Korean enterprises and educational institutions but it has remained unclear on when Koreans will be able to locally buy a unit without having to place orders from offshore online retailers.

The same case applies to Aussies interested enough to try out the gadget as tech blog site AusDroid revealed today that Samsung has been dodgy on when the new tablet will be released.

"Samsung is delighted that there is interest in the Galaxy Note 10.1 but we are not planning on making any announcements about availability in Australia at the moment," the blog site quoted a Samsung Australia representative as saying when asked on the bigger Note's specific unveiling date.

It appears that Samsung is more transparent on the second coming of the original Galaxy Note, which media reports said the company intends to unleashed before the end of August or a few weeks after Samsung has revealed that first iteration of the 'phablet' already sold more than 10 million units.

Samsung is upbeat that the Note 10.1 will become its 'hero tablet' as previous version of its answer to the market-leading iPad were either bogged down by patent clashes with Apple or were generally overlooked by global consumers despite eliciting positive feedbacks from tech experts.

But the same experts also faulted Samsung for coming up with tablets that were definitely at par with iPad but were priced closed to the bestselling gizmo. In the end, buyers ended up picking up Apple's offering, apparently not minding to pay for the little difference in dollars that separate the earlier Galaxy Tabs from the iPad.

Priced between $US499 and $US549, depending on storage size which comes at 16GB and 32 GB with expansion options, Samsung is confident that the Android-powered Note 10.1 will get more second looks as compared to its earlier siblings.

The full-sized Note tablet, Samsung said, is definitely faster and more powerful with its power-horse quad processor that speeds up to 1.4 GHz, with a complementing 2GB of RAM that ensures smooth multitasking operations.

With the Note 10.1, Samsung has introduced the 'split-screen' function that allows users to pull up two app screens at the same time. Yes, you can actually 'work' on the new tablet while surfing the net or watching the latest viral video on YouTube.

And working or studying is much easier too on Note 10.1, Samsung said, especially with the inclusion of the more accurate and responsive S-Pen (bigger too), which according to AP has been redesigned to recognise hand strokes that produce "math formula, geometric shapes, English alphabets and Chinese characters."

The only thing that lacking, analysts said, is a more tablet-friendly Android ecosystem, which is the edged cited by experts as the major reason nearly 70 per cent of tablet computer buyers around the world do not think twice in plunking down their cash for the iPad, a mini version of which could come out later this year.

The Galaxy Note 10.1 is hoped to finally drive up Samsung's global tablet market share, which as of end of June 2012 has yet to break the 10 per cent mark, based on the latest figures provided by research analytic firm IHS iSuppli.

Samsung has earlier admitted that while it exceeded Apple's smartphone sales in three of the last four quarters, its total tablet sales so far could not even reach half of what the iPad has achieved.

It remains a distant second to Apple in the tablet wars and Samsung said it intends to change that with the market entry of the Galaxy Note 10.1.
