Ok so I heard a new mac book pro just came out or is coming out soon? I bought mine 2 weeks ago. It says its a Mac OS X with a 2.4 GHz Intel Core 2 Duo processor and a memory of 4 GB 1067 MHz DDR3. Tomorrow is the last day to return this computer and if i have the old version I am going to exchange it. What is the difference between the new and old models? Also is my battery the one that gets 300 cycles before going to 80% or the one that gets 1000 cycles before going to 80%. I need to know quickly so i can return it if necessary!!!!
