Call and ask. I have one suck red pixel (from brand new) and I've learned to live with it. My only aggravation is when I eBay this iBook one day, I will have to disclose this small defect, which will in turn scare off some buyers. And that's a shame (the iMac I bought off of this forum in Feb for $1100...I sold on eBay for $1275!!).
Didn't mean to change the subject. Just ask Apple.
2,5,15? Makes a difference. I specifically have one. Hell will freeze over before Apple symphathizes with me. So how many is some? If it's less than, say, 8 or so, Apple will most likely tell you to get lost.
