I understand the difference as far as the faster ram, better graphics and all on the revB....I have a new revB 120gb and it seems like every comparison on this forum that people are making which makes revB fast and better has been from revA to revB with ssd....i didnt get the SSD model i got the 120gb model i personally cannot justify spending another $800 to go from 1.6 to 1.86 and from 120gb to 128gb SSD...granted im aware of the better technology and no moving parts...still lol...in any case I guess what I am trying to clarify is that if the new revB 120gb just as good as the SSD as far as being fast and all the issues that revA people complain about...this is will be my first mac and i want it to be an awesome experience....I have a mac mini but that is just used for HD movies lol ....detail replies appreciated thanks
