CNN Money has posted an article by David Goldman titled  “Apple tablet: One tech gadget for all”. He rehearsed the usual rumors related to Apple tablet like 10- to 12-inch screen, $600 or $800 price tag and all-in-one device that is half-iPhone, half-Macintosh computer.

The interesting part of the article came from Laura DiDio, principal analyst at ITIC. She says, “The tablet will change the game, because Apple will throw down the gauntlet at the competitors, and force them to follow along.”

According to DiDio, Apple’s tablet will have 10-inch to 12-inch screen and a high-end graphics card that will enable stunning resolution – even more so than the iPhone and iPod touch. She also believes that Apple will release the tablet in several different models that offer varieties of Internet connections, such as WiFi or 3G, perhaps through a contract with AT&T.

As we have written many times before, these are all speculations. The only thing concrete we know is that Apple is definitely working on final prototype of the tablet and the company aims to introduce the device in first quarter of 2010.
