It is unfortunate that Acer is such a small brand that Consumer Reports didn't even see fit to evaluate it in May when it last evaluated laptop reliability. What is interesting about their results, though, is that the difference between most reliable and least reliable laptops was relatively minuscule. Lenovo and Compaq (the best) were pegged at 20%, while Apple (the worst) was pegged at 23%. Consumer Reports called reliability a tie, which makes sense, after all this time: They various brands are all using the same components sourced from comparable component manufacturers, and performing assembly to the same standards, with the same relative knowledge, experience and quality of work staff.
As such, you're better-off making your decision about which laptop to purchase based on considerations other than reliability.
