Some people are still using their 10 year old ThinkPads. Wouldn't you consider a 10 year old laptop to be reliable if it lasted that long?

So your sample size of 1 is supposed to convince us that Mac laptops are more reliable than every other laptop at the same price or less?
If a sample size of "some" meets with your criteria for statistical significance, you can click on the PowerPC section of MR and find that "some" are still using 12+ year old PowerBooks.
Does this prove that Macs are better? Of course not. Early failure rates are heavily guarded. Long term survival rates don't matter enough for anyone to bother collecting data. Third party information from sources like SquareTrade is far from perfect. Consumer surveys are too subjective. Not much to go on when you really look at it. Like it or not, we all make decisions based on anecdotal evidence, but let's not pretend that there is a meaningful difference between the word "some" and the word "one" in that context.
