Currently Being ModeratedApr 28, 2010 7:47 AM (in response to Marc Bracken)Here is a link to a good article comparing the i3, i5 and i7 processors. They say the i5 wins hands down...

Currently Being ModeratedApr 28, 2010 7:50 AM (in response to Marc Bracken)Sorry to keep responding to my own post, but the i5 520M is 10W lower according to the article I just posted. Looks like it would be a no brainer to stick with the i5 if battery is the critical factor, or is apple doing something different to power down these chips?Macbook pro 2.6g, 4g memory, Dual 2 gig G5, iPhone 3G, Mac OS X (10.5.1)
Currently Being ModeratedApr 28, 2010 8:04 AM (in response to Marc Bracken)I definitely feel that the i5 is more economical with the battery, i did a calibration and I am getting about 7-8 hours out of the battery with resonable use...
Brightness 50% ish, transmission going, browser going - macrumors/light stuff
itunes going that kinda stuff, pretty impressed
i5 is where its at my man.i5 MacBook Pro HR, LED Cinema Display, iPhone 3G, Mac OS X (10.6.3)
Currently Being ModeratedApr 28, 2010 8:55 AM (in response to JohnAlanWoods)Thanks John, too bad Apple is using the lower performance version of the i5, but based on this, I will stick to the i5 with lots of memory.Macbook pro 2.6g, 4g memory, Dual 2 gig G5, iPhone 3G, Mac OS X (10.5.1)
Currently Being ModeratedApr 28, 2010 8:58 AM (in response to Marc Bracken)That's what I did, I'm telling you it's a flyer and i feel the sweet spot in the new MacBook Pro lineup,
especially with that Turbo Boost tech from intel, even the 2.4 ghz effectively operates as a 3ghz chip when only one core is loaded on the cpu, nice.i5 MacBook Pro HR, LED Cinema Display, iPhone 3G, Mac OS X (10.6.3)

Here is the final word, as Anand finally tested the i5 vs i7 for battery life...i5 is the one if battery life is your big concern

Currently Being ModeratedJun 5, 2010 12:49 AM (in response to Marc Bracken)I currently use a 13" 2.53 with SSD and the experience is perfect in terms of responsiveness, little heat generated, battery life, display ...
But as I now need much higher resolution, I am in the market for a 17" which I'd buy with an SSD (the 256 GB Toshiba in my configured online 13" MBP is perfect to me). Some more CPU power is always welcome (i7 vs i5) but a difference under 20% does not really matter to me, some more battery life is welcome too (15 vs i7) but I dread, no, *I hate heat*.
Are the Notebookcheck measurements credible?
"+Even if the i5 processors have a slight lead in many exercises in terms of performance, the i7-620M CPU reveals itself as being especially energy devouring. The CPU treats itself to about 15W more, with up to 64.7W under load, than the i5 colleagues. The test system also needs around 10W more in idle mode with 30W than the configuration with a Core i5 chip.+"
Should I try to find an "old" 2.8 C2D 17" and buy an SSD separately? What are your experiences with heat from i5 and i7 in 17" MBPs?

Currently Being ModeratedJun 5, 2010 11:01 PM (in response to Marc Bracken)G'day,
I've had My MBP i7 for about 4 Weeks, and have found its _battery life to be EXCELLENT!_
I would say I am an +average user+ who would normally use the Computer running a few Safari Windows, MSN Mac, Mail, pages and sometimes, VMware Fusion with Windows XP Pro, Microsoft Word, as well as GarageBand or iMovie too.
I do have breaks where the computer is 'Sleeping' for about an hour.
My Screen is Set to 50%, Bluetooth is off, but WiFi is constantly on.
I found that i get about *6-7 Hours use* with all of this and *Multi-tasking is never a problem with the power of the i7.*
I have not had experience with the Core i5 so I can't advise you there.
