they already do that with the i7 cpu upgrade, and the upgrade price is the same. You could argue that one is coming from an i5 2.7 and the other from an i5 3.1 but the price of those two i5's is about equal.
The HG3 was first introduced in the Mac Book Air. Almost a year ago. So they are a little older but the most reliable since the CG is the most agressive on the market today and TRIM support doesn't hurt.
You will not see a real world difference between the Toshiba drive and a Vertex 3. I have a OWC Mercury extreme pro 6Gps in my Mac Book pro and the difference between the Toshiba in my 21.5 I cannot tell the difference between the two. Don't get caught up in all the marketing hype and the numbers.

The 21.5 also has the option for the i7 2600S. Which is the same processor as the 2600 just a slower base clock, but they scale the same the i7 2.8 from 2.8Ghz to 3.8Ghz and the i7 3.4 scales from 3.4Ghz to 3.8Ghz so the performance for the two is almost idenical for both. The i7 2600S actually costs about $80 more than the 2600. So your assumptoin that they put in better processor or anything else is far fetched. I am not going to give benchmarks again for the hundreth time so I am going to cut and paste for you. You cannot just look at a base number or a base clock and assume that one is faster than the other.
You're dreaming if you think that the 27's will get different hardware or some better SSD or SATA 3. It takes months for validation, testing, and overall would be suicide marketing wise if they did so.
Where are these rumors and fantasies coming from?
(Turbo 2.0) the Core i7-2600 and core i7 2600S will power gate three of its four cores and turbo the fourth core as high as 3.8GHz. Even with two cores active, the 32nm chip can run them both up to 3.7GHz.

The Core i7 2600s will and does exceed it's TDP of 65W when the power is needed.
The core i7 2600s ability to 'scale' from 2.8 to 3.8 allows it to remain most of the time at 65W of total TDP. This is evident in the single and dual threaded benchmarks. The numbers are almost identical.
Secondly the only difference between the processors is that the i7 2600s has a lower base clock. That is it. They scale the same, regardless of TDP.
They are the same processor. Same silicon, same features. Most of the time the i7 will run at 2.8 reducing it's TDP. When applications demand more power, it will scale the same as the i7 3.4.
Look at the bench marks. In single threaded applications, the numbers are almost identical. It's only heavily threaded applications that the i7 2600 has a slight advantage, that is due to the i7 2600s having to scale to the same speed as the i7 2600. That takes a few milliseconds longer. Most of the time it will run at it's designed TDP and run at 2.8 GHz. When taxed, it will scale the same as the 2600. Exact same.
Turbo Boost 2 is innovative mainly in the way it allows the processor to exceed its TDP for a certain time (up to 25% over, or 120W on models with a TDP of 95W or 95W on models with a TDP of 65W), thus allowing Turbo Boost more of a margin. While this is obviously a bonus in terms of acceleration, it is worth asking how such an operation is possible without taking the CPU beyond its spec, and thus risking seeing the throttling mechanism kick in. The TDP is defined so the die temperature doesnt exceed a ceiling beyond which the circuits integrity is no longer guaranteed.
What Intel is actually doing is exploiting a physical phenomenon: theres a period of time before the processor actually heats up. The explanation is very simple: when the CPU is sollicited, it starts to heat up, this takes some time and the package doesnt hit its TDP right away, if it hits it at all (if the increased load lasts long enough). Thus even if the heat disippated by the processor is higher than the TDP during this heating up period, there isnt enough time for the additional heat to take the package heat over the top.
Of course, the skill here lies in managing the application of this mechanism. The longer its applied, the more acceleration you get but also the further you take the CPU beyond its spec, increasing the likelihood of setting off the throttling mechanism. Its difficult to determine an optimal value, because how much the CPU temperature increases obviously depends on the cooling mechanism used, a point that is external to the processor and therefore not universally quantifiable.
If you doubt what I am telling you google is your friend.
The benchmarks back this up. There is not much difference in performance between the two processors. The i7 2600 is the fastest quad core processor on the market. The i7 2600s is a close second. Lke 1a and 1b.

Look at the sandybridge M processors in the macbook pro's which perform almost on par or exceed their desktop counterparts.
The only reason they don't offer the better GPU in the 21.5 is because of heat issues, nothing else.
For all intends and purposes, the i7 2600S in my opinion is "superior' to the core i7 2600 providing lower power while retaining %95 of the performance.
