Hey All, So I've just got a few questions for you. I have an early 2008 MacBook Air (The original) with a 60GB hard disk and an older battery. Currently my hard disk usage is about 20GB out of the 60, but I hear intermittent ticks coming from the hard disk which concerns me. The battery is also older. Istat Pro reports that the battery health is currently 88% and OS X reports that the condition is "normal". However, the battery doesn't last more than a hour and half from a full charge. Currently Istat reports 251 cycles out of the 300 the battery is guaranteed for. So I have two options: Replace the battery and purchase an SSD Purchase a new MacBook Air I was considering purchasing the following SSD replacement kit from macsales.com: http://eshop.macsales.com/item/OWC/SMBAZIF60/ And the following battery replacement as well (or get Apple to replace it, I think it's $120 for a battery replacement): http://www.ifixit.com/MacBook-Parts/MacBook-Air-Original-Late-2008-Battery/IF188-004 All in all it looks like I would spend about $300 for the replacement parts. Some other background that would affect the decision: This is not my main machine; I also have a 2011 Macbook Pro that is used as my main machine by docking it. What do you all recommend?
