I'm trying to decide between these two configurations: 15" 2.4GHz Intel Core i5 4GB 1066MHz DDR3 SDRAM - 2x2GB 256GB Solid State Drive MacBook Pro 15-inch Hi-Res Antiglare Widescreen Display or 13" 2.66GHz Intel Core 2 Duo 8GB 1066MHz DDR3 SDRAM - 2x4GB 256GB Solid State drive This is strictly a personal/entertainment laptop. It will mainly be used for Internet Browsing/Media Downloading, Some Microsoft Office Use, Movie Watching, iMovie, iChat, etc. The 13" is about $75 less. Am I configuring overkill? Any advice/opinions are definitely welcome. Thanks!
