Maybe not, but the fact remains that in many instances, good tools deliver better results; cleaner cuts, less slop, less chipping...
I've got a friend that could care less, but he uses a lot more caulk than I do...
Having said all that, in some cases, it's not worth the premium, or the results will be the same, but just take longer. In other cases, such as as compressors and shop vacs, it's just rude to have the crappy stuff because of the increased noise they produce.
As for router bits, obviously I have a lot of $50-80 + bits, but I was referring to the basic 1/4", 1/2" shank edge cutters. No need to spend Festool's cost of $38-58 a bit, when very good bits are available for much less. The value proposition is much less. Same with driver bits and drill bits. Buy good ones, but no need to spend 300% more just cause they match your tools.
Those that dog macs usually have no actual experience with them. Resale value alone makes the increased cost worth it by many times.
Four year old Mac laptop worth $500, two year old pc laptop = $25... The lack of viruses does it for me. And for those pc users that haven't had any virus isssues, I'd bet you've spent some time and money paying for and updating the Mcafee, etc. scanning software.
Another hidden cost of those scans is hugely increased startup times. Most macs boot up in less than 30 seconds, some less.
