It seems the MacBook (6,1) could soon be up for a hardware upgrade, says engadget.
"
an unannounced MacBook update (identifying itself as a MacBook7,1) that includes a faster 2.4GHz Intel Core 2 Duo processor (up from 2.26GHz) and NVIDIA GeForce 320M graphics with 256MB of DDR3 SDRAM (an update from the GeForce 9400M found in the current MacBook6,1)
"
This would bring the MacBook to par with the specs of the entry level 13 inch MacBook Pro. Considering the price (if, indeed, it does not change) then this will be an amazing value offer (if indeed this is a true leak)
