A 50% increase in battery life is a 25% reduction in power consumption, not a 50% reduction. So they're cutting their TDP by a quarter.

Under $70. The highest spec embedded Kabini part is $72 so we can expect retail to be a bit below that.

Intel officially prices the i3 3217U at $225 but somehow I think that's not the actual price it's sold at.

"What's more, the Core-i3 matches the A4-5000 in power efficiency while its HD 4000 graphics completely outpace the APU."

While gaming, the 17W i3 is consuming nearly twice the amount of power as the 15W Kabini, at 35W vs 20W. Intel's ULV TDP ratings are an absolute joke.
