so the 'real' point of the upgrade is multitouch
and they didnt even think to make the trackpad bigger!
"Was it worth it?"
Of course it was, particularly if you've never had a Mac before. I think I jumped in right around the best time for me...I needed a new system and didn't want to wait at least another 5-6 months at least. It might not be worth it if I already had one, but for those that didn't, this is great.
I'm happy with the small performance updates. It's allowed me to join the Apple realm!
once programmers start using sse 4 the penryn MBP's will be worth the wait.
i'm assuming that sse 4 is a step up like altivec (G3 to G4). Is that correct?
This was an interim step for the MB/Ps.
Come June/July when we get the next Intel chips with possibly wimax, I think we will see a revolutionary jump not an evolutionary bump.
What I'd really like to know is:
How hot is the Penryn MBP compared to the SR MBP and what is the idle fan speed?
Anyone?

This is a misleading statement because:
1. The previous gen machine that was tested was fitted with a 7200 RPM hdd (as oppsed to 5400 rpm)
2. It had a 2.6 GHz processor (compared with 2.5 GHz).
At the same clock speed and with an identical hdd the previous generation MBPs are clearly slower than the new Penryn MBPs.
The big deal will be with developers who use the enhanced SSE4 instruction set...
"Penryn processors can perform full-width shuffles in a single cycle. This significantly improves performance for SSE2, SSE3 and SSE4 instructions that have shuffle-like operations such as pack, unpack and wider packed shifts. This feature will increase performance for content creation, imaging, video and high-performance computing." - Intel Press Release
"Penryn-based processors provide fast divider performance, roughly doubling the divider speed over previous generations for computations used in nearly all applications through the inclusion of a new, faster divide technique called Radix 16. The ability to divide instructions and commands faster increases a computer's performance." - Intel Press Release
"Penryn processors include up to a 50 percent larger L2 cache with a higher degree of associativity to further improve the hit rate and maximize its utilization. Dual-core Penryn processors will feature up to a 6MB L2 cache and quad-core processors up to a 12MB L2 cache.
Cache is a memory reservoir where frequently accessed data can be stored for more rapid access. Larger and faster cache sizes speed a computer's performance and response time." - Intel Press Release
This groundwork laid in the new MBP will mean 20% or more better raw performance out of apps that incorporate these new capabilities.
Intel has made these code changes very simple for developers to implement. You will see patches for major apps within the month.
Ah, yes. 7-15% percent is 17-36 minutes assuming a batteri life of four hours. And who can honestly say they're getting 4 hours on a MBP pro? More realistically, you get 2-2,50 and with the latter, it's a mere 10-22 minutes.
Now, don't get me wrong, _any_ enhancement is great. But worth the wait?
Nah

Thank you. I'm tired of these articles comparing the low end models and then saying this "bump" wasn't a big deal. Let's see the mid and high end MBP comparisons. The baseline model might not show much difference, but compare the previous mid-line MBP to a current mid-line MBP and you'll see a different story.
And was it worth the wait?
Well, we have a bigger/better/faster computer that runs much cooler. And to think, SSE4 isn't even really being taking advantage of yet, so one day the comparison gap is going to become even greater.
Bingo. So yes, it was very worth it.
Yup, software needs to cache up with the hardware as I stated in my post.
