I thought I would ask for some feedback from those of you who have been long time users of mac and specifically MBP's. There are so many threads about whether now is the right time to buy a new MBP or is it better to wait for the next refresh and these threads now seem to be morphing into speculation as to what the next refresh will mean in terms of spec, will the optical drive be removed, what processors will be used , what type of storage medium will they adopt as standard etc. Now it seems to me that the current line of MBP's are pretty awesome machines already but are not perfect(what is ?) and Apple will obviously change/update the specs and or design of the MBP in some way at some time in the not to distant future. My question is in your opinion have Apple ever 'messed up' their refresh, taken a backward step when changing the specs of their line up. has there ever been a refresh where the previous generation of MBP's etc were considered superior than the new?
