We just read some post on imore.com,they said:
"7-inch iPad on track for October 2012 release, $200 to $250 price"
here are some writings from their site:
We haven't gotten a firm read on the exact screen dimensions, so we're using 7-inches generically here. Our sources have indicated, however, that the 7-inch iPad will be identical to the current 9.7-inch iPad, just scaled down. That seems to include a 2048x1536 resolution display, just like the new iPad. If accurate, that would put the pixel density at around 326 ppi, the same as the iPhone 4S (and higher than the 264 ppi new iPad) retina display.
Is this true?
