I ordered a macbook 1.83ghz and had it next day aired so I would have it for the weekend. I get it yesterday and was happy until I realized the battery was defective. (The battery holds no charge - great impressions for a first time mac user) I called up apple support Wednesday evening and they went through some tests and then scheduled a replacement to be sent. I was just curious how long the battery replacement took to arrive for those of you that have had replacements sent to them. (by the number of bad battery posts, I imagine there are a few) I'm just curious if I would get it before the weekend, or have to wait until sometime next week.
