Even though a pentile screen has lower sub pixel count and thus lower "real" PPI, this is offset to a large degree by adaptive sub pixel rendering..

Actually... A 480x800 RGB has 480x800x3 addressable subpixels. A 480x800 pentile has too 480x800x3 adressable subpixels, but the controller mangles those into 480x800x2 subpixels.

Aka Pentile RGBG actually has 2/3 the amount of subpixels, no matter how you look at it.
Subpixel rendering is not only also present in the RGB layout, but is also _easier_ to do.

And just google around for 'pentile yellow pink' or 'pentile checkerboard' to see how many people detect PenTile's artifacts. Specially at a (by today's standards) very low resolution handheld such as the N9.
