I'm not sure if this has been discussed before or not, but it seems like a great time to buy a MacBook white. For 200 USD I just picked up a mid-2010 unibody with 4 gigs of ram, 250 gb hd, & 2.4 GHz Core Duo. The white MBs look dated to most, so I guess that's why you can pick one up for cheap. This one is currently running Yosemite like a dream. (Hopefully it stays that way for some time!)
