I suppose I could go out and buy a copy of every single product and try them all. But that means if I say buy 5 different ones and settle on one the money spent on the other 4 is tossed down the drain. Perhaps Mark Cuban could do that but I try to be a little more efficient with spending. It would make sense to do that if I were say consumer reports or a magazine or some other organization that had a testing lab and would recoup their money from subscriptions or memberships.
One posts on a forum to avoid having to purchase one of everything. True, nobody is likely to be able to say I have tried them all and this is best. But if anyone has tried any of them then their sharing that experience would be helpful and appreciated.
When I bought my car I did not go out and buy a car from ford, from chevrolet, buick, nissan, mazda, etc, keep the one that worked best and throw the rest away. Why do that with software? I examined all the literature I could find about the various cars and then sought out friends and gathered their opinions on the cars they drove. Nobody could tell me from experience what was the best. But the guy who owned a mustang was able to share his experience with mustangs. The friend who owned a Vibe shared what she liked about that car. The explorer owner shared their experience. And I made an educated decision from there.
Now relating that to my current inquiry. If I post on this and several other forums and several people across those forums respond with acme ramdisk is one I tried and worked flawlessly then I have confidence that might be a good use of my money. If several people across those forums post and say I tried acme ramdisk and it corrupted my system then I likely cross that off my list of programs to try.
In other words I know how to do internet searches. I know how to experiment. I know since I live in a free society I could buy one of everything, experiment and try them all. I have no reason to suspect any of the available options is unreliable. I have no reason to believe any is more likely to be reliable. Thus I go out and try to locate people who may have tried any of the options out there and are willing to share their experience.
