well that is the problem with apple care, best buy has better covarage all around. And no lemon policy is great. Simply if a laptop breaks four times, it will be replaced, and the thing is, this will be replaced with the new one, reason being that you had to do so many replacements is quite simple, apple offers a refurbished product as a replacement, most of the refirbished products where originally created on friday (joke about how everyone wants to go home and half asses the product). And the cycle of these laptops that needs repairs and originally didnt work just keeps going around. This is clever technique to maximize revenue.
You're seriously joking, right? I mean, honestly?
Best Buy's extended warranties are the worst. They lie and mislead people into buying them by saying things such as "the battery is covered!" when its not. When it does come time to service it, they will do everything they can to blame the user and get out of servicing the system. If they do actually service it, you can be without your system for weeks or even months at a time. It'll most likely come back in even worse shape than it would have if it came back from Flextronics.
They will only "replace" the system after it has had four of the SAME failures. Not four different failures. You could essentially have the screen go bad, HDD die, optical drive die, motherboard die, fans die, RAM go bad, the internal power connector go bad, power inverter for the screen go bad, etc. and they will NOT replace the system until you have had one issue four times over. Where Apple, HP, and others will replace the system after a small number of other failures out of good will just because of the inconvenience it has caused you. Best Buy will also only replace the system with one that has what they feel is the equivalent depreciated value of your old system. So let's say with HP or Apple you bought a system for $1400, they will replace your system with whatever currently cost $1400, even if its 2 years and 11 months into your 3 year warranty. While Best Buy will say "well, your computer was only worth about $700 now.." Also, Apple does NOT replace systems with refurbs. Just read around this forum. How many people who have bought their system new and had to get it replaced ended up with a refurbished replacement? None. After Flextronics destroyed my MacBook after multiple trips out to it (making it worse each time), Apple replaced my MacBook with a new model at the same exact price point as the original purchase. When my motherboard went bad in my HP, HP actually replaced the motherboard. But they called me after the repair took place and said they were going to replace the entire system out of good will. They replaced it with a system that cost roughly exactly the same, but was significantly upgraded. Best Buy would give you options as low as half of what your original system cost, IF they even ever offered to replace it at all.
Best Buy simply has the worst service out there. They will screw you over, jerk you around, break your system, swap the casing so the serial numbers don't match and then accuse you of fraud (go read consumerist.com) and many other things. They also treat their employees like absolute crap. Best Buy honestly makes Wal-Mart look angelic when you compare how they treat their customers and employees.
Best Buy also marks up the prices of iPod accessories too. At the local Best Buy here, those Apple In-Ear headphones that are set at MSRP of $39.99 (and that is what Apple and everyone else sells them for) go for $52.99. Best Buy is definitely one of those "evil corporations" people SHOULD hate.
