I'm not sure if this is Apple's mistake or not, but I can't find ANY other retailer selling a 500 GB 2.5" drive for under $200. And Apple's online store is selling a triple-interface Seagate FreeAgent Go for $170. http://store.apple.com/us/product/TT954LL/A?n=portable&fnode=MTY1NDA0Nw&mco=MTg5NTM3OQ&s=topSellers I went to the SoHo store today to see if they had any in stock. They only had the smaller two sizes... for a great deal more than what the online store sells them for. So... here's a drive you can connect to your Air/AirPort Extreme via USB, or other Macs through FW400 or 800. At $170 I think it's a crazy deal... and might just be an error.
