Most users won't notice any difference between the two processors in daily use. Those few that will likely already know how much of a difference it will make to their specific needs.
 
For $100, yeah. This has me confused on base with 2.6, or just go higher end to get the 512 ssd as well!
 
I'm pretty sure I'll be returning my 2.3/16/256 this week and get the 2.6/16/256
 
yea the 2.7 for $250 more then 2.6 that isn't worth it.. but $100 for 10% increase in performance.. I say worth it..
 
Is value is a function of what you use the computer for.

If you do a lot of AV encoding/decoding, then it makes sense. Perhaps gaming will get a small fps boost as well. Otherwise, the 2.3 is just fine. Don't pay attention to those who blindly recommend it without even asking what you use the computer for. If you're doing regular computer stuff (browsing the web, document creation, iTunes, etc.) 2.3 is more than enough. You'd never feel or appreciate the extra 10% from the 2.6.

If you can list the applications you use on a daily basis, a proper recommendation can be offered.
