Sounds like you at least got fast replacements. My Dell was deemed defective so they said they were going to send out a new one. They said I'd have it in two weeks??!!!!!!!??? I looked at my warranty and told them it CLEARLY stated NEXT BUSINESS DAY REPLACEMENT. (Which it does) According to my order, it won't even SHIP until the 17th. I placed the trouble call and replacement on the 9th. (Sunday) That doesn't seem like next business day to me. I'm EXTREMELY po'd about this. I've read over the warranty very carefully. If they can't deliver what they promise, then they shouldn't put it in writing.
Not very happy about this at all.
Glad everyone else had good experiences. Maybe something will change.
