People continue to love their iPhones. The results of J.D. Power and Associates' latest customer satisfaction survey are out and they are unsurprising:

For a sixth consecutive time, Apple ranks highest among manufacturers of smartphones in customer satisfaction. Apple achieves a score of 838 and performs well in all factors, particularly in ease of operation and features. HTC (801) follows Apple in the smartphone rankings.

The reasons why Apple's on top again make sense. Based on the marketing information company's research customers care most about the "physical design and dimensions of the device," including weight and thickness. J.D. Power's Kirk Parsons said, "Having the right combination of physical dimensions and operating functions and features for both smartphones and traditionally equipped devices is key to creating an exceptional ownership experience with each type of wireless device."

It's worth pointing out that the only year Apple didn't win the J.D. Power survey was in 2007, the year that the iPhone came out. Research in Motion (RIM), the makers of BlackBerry devices, won that year, but it's likely Apple wasn't even in the running since it came out only three months before the report. This year, it was BlackBerry that didn't earn a mention. We'll just add that to the list of everything that's going wrong at RIM.
