The "Should I buy a Mac?" example is good to consider. What if I have no life experience with Macs? Isn't the experience of others worthy of consideration? Perhaps others' experiences aren't relevant. I'm sure Macs help a guy talk up more women at coffee shops, but a married guy wouldn't care so much.
Speaking as a guy who was single when he got a Mac, has dated since getting his Mac, and is single once again, the Mac has nothing to do with dating unless you're really desperate and willing to go after would-be hipsters. In fact, dating has no consideration when getting a Mac. You get it because it's a beautiful machine that feels wonderful.
I have a sinking suspicion that the people who are that sensitive to beautiful things get more dates than people who have less taste in things, but the two are not directly correlated.
What's wrong with making your own decisions based on passed experience?
