Hi - Considering buying a mid 2012 macbook Air off of Craigslist. Assuming the machine is in good working condition (i haven't seen it in person yet) what do you guys think of price for the specs? 2.0 iCore7 Ivy Bridge 8gb RAM 256SSD Asking $900. This is a little more than I would normally spend for a used laptop, but the configuration is $1599 new and it's less than a year old. My alternative is a base MBP and possibly upgrading RAM/SSD in the future when prices drop some. Thoughts? Many thanks.
