Hi everyone, I am finally buying a MB within this week, but I have a few questions. It would be great if someone could answer these for me. I am going to switch do its my first MB. I am a student so I decided to buy a Refreshed MB from the apple store, so do I just go to the store and ask them if they have a Refreshed MB? What do I have to keep in mind after I buy the MB. Do I open it in the store and check if everything is ok and working. Also the I have seen the Refurbrished MB on Apple Online and it comes only with a 512 mb RAM, So how do I increse the RAM, DO I buy extra RAM from the store and ask them to install it, or do I buy it online and do it myself, if I buy it from a 3rd party and install the RAm will it Void my warranty. I have no idea what to do here. Also I have read somewhere in the forum about the battery cycle or life. DO I have to charge the battery before I switch my MB for the first time, or I can just start using it out of the Box. How do I protect the MB from scrathes and stuff, is there something out that I can use to protect it. One last thing, I am also looking to buy a backpack for the MB, but I need something which can also hold my camera, I have a Canon S3, can anyone recommend any good backpacks. Thanks and any recommendations is greatly appreciated. I am excited, thrilled and at the same time a liitle confused. I don't want to make any mistakes buying my first MB, so Please HELP!!! Cheers!!!
