Dual-core doesn't necessarily chew more power, unless you're loading both cores constantly. If anything the secondary core will spend most of its time asleep, moreso than the primary core, and not consume much more power than it would were it not there.

In return, you'll get a more responsive device because you'll probably have a CPU ready to do what you need if the other is busy.

not a must be...

e.g. some time ago nvidia mentioned regarding their soc that more power means less time for the cpu until his job is done. and that means that the cpu can go to his power saving modes faster then with a single core cpu...

That doesnt make any sense!

Whats all the Vodafone packages about? as it already got carrier support? customization?

If you're still talking about the google link, it's OMAP3:

I'm not sure, but I don't think Apple significantly changed the battery for the latest iPad. If that's true, you have single core and dual core ARM devices with very similar battery life. 'nough said.

you can speculate as long as you want about the CPU. It won't change^^

okay, next small hint:
Why is there a bezel around the screen, which looks exactly like the screen?
