As the anticipation for the launch of Apple's next-generation tablet, presumed to be called the iPad 3, grows, apparently the very first review (or preview) of the tablet is already out.

iLounge claims its sources already have sighted a pre-production model. And according to a review by Jeremy Horwitz, iLounge editor-in-chief, there would be no 'dramatic change' except that the body will be about 1 mm thicker.

From the front, the next iPad and iPad 2 appear to look basically the same—apart, of course, from the screen. That’s going to be Apple’s big focus when the new device is announced, but I didn’t see it, he said.

On the rear, the camera in the upper left corner has become bigger—noticeably so when placed alongside the iPad 2, but not so huge that anyone would think they were different at a distance.

These changes are so modest that Apple could easily call this device the 'iPad 2S,' Horwitz concluded.

With the competition on the rise, iPad certainly faces a tough road ahead in 2012. Will the world's most popular tablet not only survive the race but also win it? Or will it fall behind Android tablets? It's too early to tell, but one thing's certain: Apple needs to come up with something revolutionary to stay ahead of the pack.
