Are there any performance benchmarks of the Intel Core M (Macbook) vs 2.5GHz dual-core Intel Core i5 (MacBook Pro). The new keyboard, new touchpad, new design, improved battery are awesome, but for nearly the same price, you can get a MacBook Pro.
Eh well the M isn't even as performing as the MBA lineup, let alone the MBP lineup. I wouldn't expect the MB to be anything near a powerhouse.
And the MBP 13' has better battery life by 1-2 hour than the MB. (not the non-retina MBP, which is 2 hours worse), but the retina (which is priced the same as the MB. (although you'd need to add 128gb storage to make it equal which increases the price a bit).
The keyboard doesn't actually seem any better. Yes it's backlit by individual button and yes the buttons are a bit bigger than normal with a new system. Is that better? I'd say it looks like they did a good job of not making the keyboard suck more. After all, they have less space for the keyboard as it's 12' big, less travel for the keyboard as it's thinner. But less travel is generally worse, less space between keys (more mistakes) is generally worse, keys right next to the touchpad is generally worse.
So I'd prefer the MBP keyboard and battery, the MBP screen, CPU and Graphics, magsafe charger and ports.
The MB's pros is the touchpad (will have to try it first, looks interesting but I doubt the 3rd click will see much software support the first year anyway, beyond that it's nothing new). And the fact it comes with 256gb at the same price. But it doesn't make up for a shitty CPU and graphics, tight keyboard with little travel, 1 port requiring externals, 1-2 hours less battery and 1 inch less screen.
If I wanted the smaller form factor I'd still go for the MBA 13'. 3 hours more battery, extra inch, a lot cheaper, better performance.
Sorry couldn't answer your specific question, haven't seen benchmarks, just know the M sits between their low-power low-performance chips and the i5/i7 core chips. The fact it draws 5 watt and is fanless tells you enough :P
