Because in order to achieve the small form factor, Apple solders the CPU to the motherboard, which means they are not swappable. There is no way Apple's has the resources to solder a different CPU to every MacBook according to every customer's whim.

Intel Mobile Processors to be Refreshed in April? Nehalem Soon After
- Thread starter MacRumors

When we compare TDP of penryn cpus vs nehalem, nehalem can be slightly higher but overall platform will still be lower bcos of built in IMC. So T series will be 45W while P series will be 35W under clarksfield. I am sure there will be few quad cores in T series and a couple even in P series. I believe nehalem will make quad core mainstream. So I will not be surprised if MBP goes entirely quad core.
Auburndale with built in gfx will come later. I expect MB to stay dual core.
Performance wise I dont see major upgrade. T9900 at 3.06ghz and 35w should match similar clocked nehalem.
I am hoping intel does not delay 32nm too much. I am sure TDP can be lowered further on 32nm.
Sandy bridge(next architecture) is from haifa team and would hopefully be mobile focussed like core micro architecture.

A T series CPU doesn't make much sense to me in a portable device like the MB.
NOTE: Switchable Graphics Support
This love affair with Nvidia will be short-lived. By the time Snow Leopard arrives, Nvidia, AMD/ATi and Intel will all be switchable gfx supported.
The charts make it clear that Intel will quickly have this feature set.

??? Intel's Centrino 2 does support it. Notebooks with Intel X4500 and additional nVidia GPU can do it.

The current GM45 chipset already supports switchable graphics and Intel's implementation is of course GPU agnostic so you don't have to lock into nVidia GPU product line or ATI GPU product line. Like this Lenovo that can switch between the GMA X4500MHD and a Radeon HD3450.

And Sony even figured out how get switchable graphics working on the GM965 and the GMA X3100 like what was used in the previous MacBook. The Sony switches between the GMA X3100 and a nVidia 8400M GS.
Yeah, I suppose a lot of people don't and I could live without a laptop for school purposes but I need my own computer for well fun too. Heck I am a member of a website based on MacRumors, I care a little more about my computer then just typing up papers and looking things up on Wikipeida to write those papers.
iTunes, e-mail, Hulu, facebook, games, ect. I need to be able to install my own apps and just have a computer, but hey I am looking at going from a 2ghz G5 iMac so even a MB Air would smoke it, so I guess I will be happy.
I think you're mistaken, clarksfield are quad-core only. There will be no 35W clarksfield (at least at launch). What is currently a 45W part (Q9100/QX9300) will become a 55W part under nehalem. What should be a 35W part (Q9000) will become a 45W. The current dual-core (auburndale) will also have their TDP increased due to the integrated memory controller (and gpu) so current 35W part will become 45W, and current 25W parts will become 35W. TDPs of LV/ULV nehalem are still unknown.
You can install and run nearly any application on a lab Mac. If you can drop it into user space it's all yours. I've informed professors that they can install applications onto their desktops when they were only given standard user access.Yeah, I suppose a lot of people don't and I could live without a laptop for school purposes but I need my own computer for well fun too.

In addition you can probably get any with installing any application you can in Windows. I had Trillian and TeamSpeak in my home directory. DeepFreeze the weapon of choice on Windows and sometimes on Mac. I've had quite a bit of fun playing Command & Conquer: Red Alert and Joint Operations: Typhoon Rising in the computer labs back in my PowerPC days.
If you've living in a dorm open up file sharing on your Mac and abuse your static IP address. (If you're lucky enough to get on at your university.)
I'm rather sadden that your instructors allow you to use Wikipedia as a source to be honest. Don't you have a library or database subscription from your university? I was also good friends and still am with the campus Macintosh administrator.
right. And besides the fanfare we're seeing with the current relationship with this round of laptops, you're going to see Apple having more choices as OpenCL and GrandCentral are available. Instead of Apple being bound to a single vendor, they can pick n' choose.
They are already out for the mobile workstations from Dell, HP and Lenovo. I expect the MacBook Pros will get them this January. I was hoping the 17" MPB would get one and Quadro video card on the 14th with a larger, redesigned case that could also hold two hard drives like the other mobile workstations can. Maybe at Macworld.
Whim ? Different customers have different needs Is Apple a small mom and pop computer shop that can't afford to offer more than two or three models ?
I really don't get it.. Why upgrade in April to a Peryn Processor when in July/August you'll have Nehalem + Snow Leopard??
April's upgrade would be useless, don't you think? .. unless you really really really need it
Who told you Nehalem for notebooks is coming in July/August? You will have to wait at least a year. On top of that Intel likes to delay things anyway.

It is because in Q3, only quad-core cpus (Clarksfield) will be available those will probably be 45/55W parts and I don't think Apple will use most of them in notebooks. But they could use them in iMacs.
Dual-cores with or without integrated GPUs will arrive later (late Q4 or early Q1) with TDPs of 35/45W. Some of those could be used in notebooks.
Probable calendar:
- Late Q4 2008/early Q1 2009: iMacs/Mac mini + Nehalem Mac Pro
- Spring 2009: notebook refresh/speedbump
- Summer 2009: snow leopard
- Fall 2009: nehalem iMacs (possibly all quads)
- Q1 2010: nehalem notebooks/Mac mini + Westmere Mac Pro

and if I not wrong Calpella will be the chipset for Nehalem.
Nehalem for desktops will start to be shipped final of current year. So i would say more 6 months for notebooks... I hope

Given that CPU schedules always slip, and that we'll probably have to wait through next year's iPhone/iPod updates, I'd guess we're more likely to see Nehalem-based laptops at MWSF '10. Six months is far too short a time for a development program for a new laptop platform anyway. From design through several rounds of production and testing takes more like a year.
Actually the "good" relationship with Intel, let apple be the first to release the MacBook Air's processor, and I think the new notebooks are the first notebook with the new montevina platform with DDR3 capability (but I'm not sure about that). So I hope the MacBook's will be the first notebooks with a Nehalem processor. That's a race Apple don't want to loose for Windows 7. I think the release date of Snow Leopard and Nehalem processors will be very close.
Montevina-based PC laptops were released months ago, and the new Macbooks don't even use Montevina.
Desktops will be first, laptops later - end of next year.
No, but they are Montevina's based. DDR3 is not from Santa Rosa's for sure!
servers will be first, desktops later, then notebooks.. IN AUGUST !!!
Mobile CPU speeds (and Core 2 in general) have been stalled for a very long time. This is really a small bump and we should be seeing 3.33 GHz +
It's not necessary when you can do more in a clock cycle. Intel is constantly updating architectures to make the same instruction take fewer clock cycles. For example, Nehalem will incorporate a new divider architecture to replace one that has persisted for years and years. Additionally, making the architecture able to exploit ILP better allows more instructions to be executed per cycle.
Increasing CPU speed is a brute force way to improve performance.
