...there is also no publicly available evidence that Time Capsules have a longer lifespan
I doubt that there are many, if any, forums tallying reports of Time Capsules that are run fine.
So, what does the number/value tell us? Maybe that investing in AppleCare would be wise? Possibly that electronic devices are becoming
more reliable, since the common knowledge is that these types of things either fail within 60 days or last "forever?" A more reliable and useful number would be the ratio of failed units to units sold and still in service. That time is relatively useless as it gives no real information on how to change the number. For example, how many 'failed' units were repairable? How do the hard drives used in TC compare to all other hard drives in reliability? How does this product compare to similar products by any manufacturer. How does the 'real life' failure time compare to pre-release testing?
It is a generalization at best and misleading at worst. Just as we expect TS to be mainly populated with trouble reports, that site would be expected to contain mostly "dead Time Capsule reports." If we based our purchasing decisions on reports of problems alone, we'd probably still be using typewriters. After all, they didn't break nearly as often as early computers, consumer
or commercial!
Remember, the term "bug" came about because of actual insects that short circuited early computers. Those same bugs never bother a Remingtons or Royal machines!
Of course, if Apple has more reliable figures on failures and does nothing to improve them, they are either very low numbers/percentages or they are acting unethically and unacceptably.
