Asustek Computer again managed to become the maker of most reliable personal computers in the U.S., according to Rescuecom’s quarterly computer reliability report. Apart from Asus, Apple and Lenovo Group are in the top three makers of most reliable PCs. Even though the scores provided by Rescuecom are rather questionable, they outline a rather alarming trend: the amount of calls requesting support for Asus PCs is increasing quicker than the market share of the firm.

“Because Asus just introduced the newest version of the Eee PC laptop last fall, the original predicted computer reliability of this laptop has been somewhat up in the air. However, a good eight months later, we are still receiving the fewest calls for computer repair and support with Asus, while their market share is increasing, adding the Eee desktop to their line as well, indicating that this PC is continuing to prove itself in terms of computer reliability,” said David A. Milman, the founder and chief executive officer of Rescuecom.

But while Mr. Milman praises reliability of Asustek’s system, there are two points that need to be noted: firstly, reliability score of Asus systems in Q2 2009 dropped dramatically to 416 from 972 in the first quarter; secondly, while the U.S. market share of Asus increased to 2.5% from 1.6% in Q4 2008 (an increase of 56%), the share of calls requesting tech support to Rescuecom raised to 0.6% from 0.2% a quarter ago (an increase of 200%). Reliability scores of Apple and Lenovo remained on approximately the same levels.

For the second quarter of 2009, IDC reported a total of over 16 million shipped PCs among eight major brands. Over this same time period, Rescuecom received 11 560 calls for computer repair and support related to these brands. "Computer reliability" is based on two key measures, including the quality of the components and software that's used in manufacturing the computer, and the post-sale support that's provided by the manufacturer to its customers. The higher the score, the greater the reliability of the brand. The top five contenders and their computer reliability scores are as follows:

"When it comes to buying a computer, quality of components and service by the manufacturer after the purchase play a big role in consumers' purchasing decisions. Our reports deliver the most up-to-date information, based on our ability to define and predict the anticipated reliability of today's most popular PCs, minimizing the need for computer repair during the time you own it,” added Mr. Millman.

But not everything is that simple. What should be noted about the Q1 and Q2 2009 reports by Rescuecom is that in previous years the reports calculated the “reliability score” for each PC vendor based on the calculated difference between overall U.S. market share, over a three-year period, and the percentage of calls requesting service received by Rescuecom call center over one specified quarter or one year. However, starting from 2008 the service company started to compare the amount of calls over a specified period with the approximate market share in that period (or take market shares from a couple of previous quarters).

This new methodolody substantially alters the outcome as complaints regarding older systems are compared to current market shares. As a result, if a company owned 10% market share three years ago and now has 5% of the market, it will get lower reliability score since it is natural that older systems need more attention from tech personnel. The same is effective in other direction: a company with 10% market share now that used to command 5% of the shipments will get higher score since proportionally to current shipments the amount of complaints will be low.

Well, the more computers sold by a company, proportionally, will create more service calls. Flawed stats....

No, the stats are produced by comparing share of the sales market with share of the support market, so to speak. The assumption is that if all computers are equally reliable, they generate support calls corresponding to their market share. Hence, if a company sells 5% of all computers but generates 10% of all support calls, it has low reliability, where if it generates 2.5% of support calls, it has very high reliability.

The problem with the stats is that market share won't necessarily equal support needs. Suppose you sell 2000 computers in 2008 and 1000 in 2007 while sell 1000 in 2008 and 2000 in 2007. We both have the same total share of the market, but because my computers are on average older, you would probably expect more support calls for them. That's where the real flaws in the stats arise.

This is exactly why they compare only the leading vendors.

Problem is that they add calls that support IBM (which is the brand that has been out of the PC market since 2006) to Lenovo machines, which degrades their "reliability score" since those systems are simply old and are naturally going out of order.

Sad moment here =(. Just bought an HP DV6 (Turion Ultra ZM-82 and mobility HD 4650)...hope I won`t have issues with it...

Given how few Apple users will actually call for help someone who is not employed by Apple, it is very surprising that they are not at the top of the list! Oh, almost forgot, most of them buy new apple gear every 2 years.

Flawed methodology + inconsistent data + inconsistent manufacturer's policies (from apple to Toshiba) = useless data.
