I played with a 2011 MBA 13" for a day recently and loved everything about it except the size (itching for the super-portable 11" MBA myself). The battery life was excellent, with the battery monitor hovering within the "5-7 hours remaining" range throughout a days use until slowly dropping to about 2.5-3 hours juice left. I spent the day doing easy tasks: Word, iTunes listening, minor web surfing. Kept the screen light fairly low to preserve battery life. I'm a little concerned about the the smaller battery in the 11" MBA. I read a lot of complaints about it not being enough battery to make the laptop worthwhile. Given the simple tasks I listed above (I'm not a gamer or video/photo editor or anything), how much battery can I assume to get out of an 11" MBA? The full 5 hours the item is listed as, or more like 2-3 hours? I'm currently rocking a 2008 MBP that dies after 10 minutes of battery use when not plugged in, so honestly, anything is an improvement for me! OH.. and when it comes to refurbs, is the battery power just as strong as a brand new MBA, or does it suffer from whatever prior use the previous owner gave it? Thanks!
