OMAP2420 was designed for lower-resolution screens and not for 800x480. Therefore the integrated framebuffer controller could not be used and the stock powerVR driver would not work. You can get opengl es on their lower resolution phones.

A second reason is the fact that Nokia did not position the tablets as gaming devices, and so there was no business case to invest in OpenGL support.

To go even further offtopic here, I am beginning to agree with their decision. Making the devices suitable for gaming would lead to a design like the pandora.



The pandora is designed for gaming and emulation and has optimally positioned dpad, buttons and dual analog controllers. Incorporating such controls onto a Nokia tablet would ruin the aesthetics for users who want mainly/only an internet tablet.
