WAYNE, N.J. » Toys R Us said Monday that it plans to launch next month its own tablet computer aimed at children, introducing a low-priced entry into the increasingly crowded tablet business.

The news comes ahead of the holiday season, which can account for up to 40 percent of retailers’ annual sales. Toys R Us has focused on exclusive toys rather than discounts as it faces tough competition from online retailers such as Amazon.com and discounters including Wal-Mart Stores Inc.

The Toys R Us 7-inch touch-screen tablet, called "Tabeo," will come with 50 pre-installed apps selected for children, including games such as Angry Birds and Fruit Ninja, and a book app called istorybooks. The table will be equipped with Wi-Fi and run on Google Inc.’s Android 4.0 operating system.

It will be launched Oct. 21 and retail for $149.99.

Toys R Us sells other electronics including Apple Inc.’s iPad, but this is its first store-brand tablet. Tabeo’s main competitors include LeapFrog Enterprises’ LeapPad, one of the biggest hits last holiday season, and VTech’s similar InnoTab.

The introduction hurt shares of LeapFrog, which fell 80 cents, or 8.7 percent, to close Monday at $8.35. The stock is still up about 49 percent since the beginning of the year.

Children’s tablets are increasingly popular. In addition to the LeapPad and the InnoTab, other children’s tablets include the Kurio Kids Tablet from TechnoSource and the Meep Kids Tablet from Oregon Scientific, both matching the Tabeo’s $149.99 price tag.

Meanwhile, the adult tablet market has been heating up. Last week, Amazon unveiled a $499 4G high-definition Kindle, a $299 Wi-Fi HD model and a smaller 7-inch Kindle starting at $199. The most popular tablet remains Apple Inc.’s iPad, which starts at $399.

Needham & Co. analyst Sean McGowan said it is hard to say how a new kid-oriented tablet will fare since the market is so new, although LeapFrog’s LeapPad proved popular last holiday.

"Toys R Us’ Tabeo appears to offer great value, but the challenge with Tabeo will be keeping the product from occupying an awkward middle ground — not quite cool enough to get people to spend the money, but not cheap enough to be an impulse purchase," McGowan said.

In the privately held retailer’s most recent quarter, which ended July 28, its net loss widened slightly from a year ago, hurt by weakness in Europe and a decline in video game sales.
