Hi everyone, I'm new to the forum. I'm getting ready to upgrade to a new MBP (I currently have a 12" Mac PowerPC which has served me well since 2005) and am wondering which actual MBP 15" configuration is available at Apple retail stores. The reason I ask is that I'm cheap and don't want to pay sales tax. So I'd like to buy my MBP in Delaware (no sales tax). I'm looking to buy a MBP 15" Matte Anti-Glare Hi-Res with the basic configuration: 2 GHz, 4 gb ram, 500 gb HD 5400 rpm. Does anyone know which configurations are actually available at the retail stores? Thanks!
