Sony, worried that Apple will take over the tablet world in the same way they did the MP3 market, is rumoured to be working on a all-in-one device that "shares [the] characteristics of netbooks, electronic-book readers and handheld-game machines."

While nothing has officially been stated by Sony, that hasn't stopped the journalists at the Wall Street Journal in the US talking "to people familiar with the matter," to get the low down and dirty on the next big thing.

The article, which then seems to go on by shoving as many rumour buzz words in the article it possible can, also suggests that "The device is designed to compete against multifunction products such as Apple's coming iPad tablet."

If that wasn't enough to get your gadget juices flowing, the WSJ also claims that the company is working on "a smart phone capable of downloading and playing videogames," as well, resurrecting rumours of the PSP phone once again.

Both "The new products are targeted for launch in 2010, although many details such as price and certain specifications have yet to be finalized, these people said." Claim the WSJ.

If that wasn't enough to keep Sony busy for the near future, it will also supposedly be revamping its PlayStation Network Store to allow it to deliver all the goodies the new device will need to make it an iPad challenger.
