In just a few years, the tablet computer market has become a crowded field, with devices available from major tech manufacturers including Apple, Samsung, Acer and Motorola. That market has widened further with the announced upcoming releases of the Kindle Fire from Amazon and the Nook Tablet from Barnes and Noble.

However, according to Computerworld, a number of analysts familiar with the tablet   and tablet computer accessories market have stated that none of these devices will be likely to provide significant competition for the Apple iPad or iPad 2, the two products most likely to continue their domination of the field.

Forrester Research analyst Sarah Rotman Epps believes that while the Nook Tablet and Kindle Fire in particular have the advantage of low prices on their side – $249 and $199, respectively – and are both likely to be successful, neither will genuinely threaten the iPad's status at the top of the tablet heap.

"If Apple keeps selling iPads at its current rate, it could sell 20 million worldwide in the fourth quarter [of 2011]," Epps told the news source. This is higher than her Q4 estimates for the Nook Tablet or Kindle Fire, which she places at 1.5 to 2 million for the former and 3 to 5 million for the latter.

The Washington Post reported that the Nook Tablet's major features include pre-loaded Hulu and Netflix apps for movie and TV streaming, 16 GB of data storage and nine hours of battery life when playing videos.
