Corsair is without a doubt one of the most popular memory brands used in performance systems, and most enthusiasts have used or at least tried Corsair RAM. If you're one of them, you'll be very interested in a recent interview with John Beekley, VP of Applications Engineering for Corsair. Rather than asking specific questions regarding new products, it's a more down to earth interview in which it's obvious that Mr. Beekley is trying to make Corsair appear friendly in the eyes of the consumer. He talks about performance profiles and DDR2 memory, along with Computex and Corsair's USB drives. There's a brief mention about up and coming technologies like DDR3, but what was most interesting was Mr. Beekley's response when asked about the lifetime warranty and the obvious inclination of enthusiasts to overclock and overvolt Corsair RAM:

Well, we design and qualify Corsair products with a bit of abuse in mind! Generally, our parts are pretty rugged, and more than handle the treatment that our customers give them. So, our return rate is very low. This low return rate enables us to replace failed modules pretty much no questions asked. We spend a lot of effort supporting our customers and helping them tune their systems; they generally return the favor by not returning parts that they have destroyed by overvolting them too far.
It's definitely worth a read, even if you aren't a Corsair fan.
