Nevertheless, what you say is not true. This is the CPU review:
So they were nearly identical in Sunspider and the Xoom beat it in browsermark.
Regardless, it's a non-sequitur for the purposes of this thread: you're saying you like the TBolt even though it's not dual-core, because the PowerVR GPU bested the Tegra2 GPU. That does not logically follow. All that matters is whether or not the dual-core implementation in a TBolt would be better than the current one. No idea why you are spinning things based on your preference, but don't distort the facts to justify it.
