Not convinced this is a dual-core device.

As pointed out in the article, the "up to 3x faster in some tests" is based on GLbenchmark, which is an OpenGL suite of tests and (as pointed out in this forum post) the original 1GHz SnapDragon (presumably as used in the HTC EVO) had a poor GPU.

Presumably the new 1.2GHz SnapDragon SoC in the Glacier now has a better GPU explaining why it is slightly faster (on GLBenchmark) than the 1GHz clocked Samsung Galaxy S (which already had an updated GPU) - the difference is due to the increased clock frequency of the single core ARM in the Glacier, not the presence of second core.

For the record, I'd prefer a slower clocked dual core device (eg. dual 600Mhz-800Mhz) than a fast clocked single core device (1GHz+), and a highly clocked dual core device is probably ridiculous/overkill.

Agree that MeeGo is probably best placed to exploit SMP but tweaking the VM may be all that's required in order for Android to make better use of additional cores.
