I'm going to buy a 15" Macbook Pro and I want to do it online, mainly to save the tax, which in CA is about $270 on the system I want. Does anyone have any favorite places to buy that give good rebates, preferably cash or free RAM? I'm not interested in inkjet printers. I've looked at Amazon and CDW. There's a Macmall in my town, so no tax savings there. Also, does anyone who bought one of these have any advice on drive and ram options? I want to use Avid, so I'm thinking 3g ram (avid doesn't recognize 4 for some reason). Hard disk size? Was the one you bought too small or just right? I'm excited about it. Please help.
