because the GPU used in the TI Omap3 SoC's is the SGX530, which is already less powerful than the current Samsung/Apple SoC's which currently sport the SGX535.

given that the MeeGo app/games market is likely to start very small, it will receive cheap ports at best which means it needs a performance advantage.

The new hummingbird chip uses the SGX540 gpu, and will be turning up in phones very soon.

This is why Nokia need Omap4, not just for the dual-core A9 CPU, but because it too incorporates the SGX 540 GPU.
