Looking for some input before I head to the genius bar this evening. I have a late 2009 2.26mHz white MacBook (rubber bottom) and the battery is past 1,000 cycles. I ideally would like the computer to make it to 10.9 and at least 2 more years so I am doing a battery replacement. I have 2gb ram and do use the computer for video encoding, audio editing, screen sharing and do often leave it charging to work for a day or two on projects. Does anyone know what Apple will charge to do a ram increase to 4gb? I know it is cheaper elsewhere but I am not confident or willing to do it myself and there aren't a lot of convenient authorized resellers. I figure if I can do both for 1/3rd the cost of a replacement I can extend the life of this one. Curious if anyone can tell me what cost I would be looking at and pros and con opinions on the upgrade.
