So I recently bought a 2008 Macbook. I bought it from some dude at a fleamarket for $30, and it didn't have a battery or harddrive. I originally thought it was a 2009 model, but found out it was actually a 2008 model. So I have a couple questions. First of all, are these computers even still useful? The CPU doesn't seem too weak, but I'm scared about the Intel GMA graphics. Second of all, I have a hard drive, but it's blank. Do I have to buy some sort of install disks? Or how do i get the OS on? Can I use a USB flash drive and torrent a copy of Snow Leopard or something? Last of all, if it actually is useful, where can i get a decent battery. I'm gonna go with a used one, hopefully I can get at least 2 hours out of it.
