Hello guys, Im getting a ultimate macbook air 13" in a month. Basically i want to keep this expensive machine as much as possible, perhaps 3 years or more! I heard that the ram is soldered which is why im getting the 4gb ram but is the battery soldered aswell? since im planning to use this laptop as much as possible im sure i will need a battery replacement in the future and it would be awfull if i couldnt replace it!. Im asking this to make sure im getting a safe buy ps: I heard only the 2008 MBA battery can be replaced while the 2011 not <- please tell me this is not true. Thanks in advance!
