an iPad with 326 ppi would be great for eBooks though, and it would vault the next gen iPad over other tablet computers.I doubt iPad will get a display with same ppi as that would need 3 times more pixels in iPad which would be about 1920x1080 i.e. INSANE! Possibly an improved display in next gen but not that high ppi though.
A high res screen will be found in competing phones. In fact, some were already farther along than Apple until iPhone 4 came out.
The Nexus One managed to achieve an extremely impressive 800×480, but only by using the PenTile matrix to 'cheap' by eliminating some sub-pixels, so it's not truly at the same high pixels-per-inch ratio, as there are less green sub-pixels- and the screen is bigger, to boot.
The iPhone 4's screen completely demolishes anything else out there.
Let's be honest, though- Apple blew everyone away.....
