Hey there, Got my MBA 13'' at the beginning of this month and absolutely loving it. I also purchased 2 sleeves (one ACME made, 'open' sleeve for when using it frequently, and another zip-up sleeve for longer period storage). I do however have one weird question about the sleeves - what direction is one meant to put in the MBA? Front (open bit) first? Or the other way round? Obviously, it fits both ways, but I don't quite know which way is 'correct'. Next question is regarding battery life - Is there any way of knowing how long the MBA has been off charge? So I can actually test the battery life once it reaches, say, 1%? Thanks!
