I bought a Dell XPS 8300(one of the affected chipset models) at Best Buy on 1/6/10. I just recieved this letter yesterday and was not very happy with BB for a few reasons.
#1. This issue has been known for almost a month and a half and it took BB that long to issue a statement(they had my home address and email address from day 1). Dell contacted me via email almost immediately(which leads to-
#2. The solution for this issue has already been decided many weeks ago(and Best Buy has/had nothing to do with it). You don't have to to take your computer ANYWHERE or waste ANY of your time. The option Intel and the OEM vendors(i.e Dell, HP, etc..) came up with is much fairer to the consumer(being that the consumer had nothing to do with the flaw and , therefore, should have nothing to do with the fix) and , again, was announced WEEKS ago. Call your OEM vendor(you're warranty is through THEM, not Best Buy - unless you purchased the overpriced Geek Squad option), they will dispatch a technician TO YOUR HOME with a new fixed motherboard(now available)and do all the work for you. Why should the consumer have to take ANY of their time to drive back to Best Buy.
#3. I've already spoken to Dell Support about the infamous BB letter and they were LIVID!!!!! They told me to rip the letter up and Best Buy will be duly addressed for their breach of protocol in regards to the appropriate Mobo replacement option(which, by the way, isn't mentioned once in the letter). Also the OP didn't quite get the exact flavor of the purposely vague and ambiguos BB letter. They don't come out and say they will REPLACE your computer. The letter says thet will have new stock on 4/3/2011 and you can either return your computer(and I'm sure they will stringently stick to their 30 day return policy on that option) OR you can re-PURCHASE a new model and they will transfer your data for free or if you choose NOT to purchase a new model from them they will transfer your data to a measly 320 GB WD HDD(the HDD in mine is a 1.5 Terrabyte , so that option is an absolute insult to me). Nowhere in the letter does it guarantee that the consumer will be getting their money back for the original computer purchase. The ONLY thing the BB letter guarantees is the free data transfer(whooopie!!!!!)
#4. In my opinion, this is just a scam by Best Buy(being that the letter never mentions the actual Intel/ OEM mobo replacement protocol) to get unwitting and non-computer savvy consumers BACK into their store to either try to rip them off by selling them a new computer(without giving them any credit for their old one) or over sell them on higher priced computer - and maybe they'll grab a new iPhone 4 on the way out. It's reprehensible on BB's part in my opinion.
