Technology as Religion is an issue I have only recently begun to recognize in myself, and have completed eliminate as a result. I used to pick "Favorites" in technology, for completely stupid reasons, sometimes no better then just being more familiar with one then another. Fanboys, fangirls, appleheads, windows geeks, whatever you want to call them - they're all groups with inherent bias.
My new motto is, "It's technology people. Use whatever the fuck gets the job done for you." I dismiss no hardware, software, or OS. If you want to wax poetic and argue over how the VAX 4000 is far superior to the VAX 6000 or some other pointless bullshit (ford/chevy style arguments) , go right ahead and argue with the VAX 6000 idiot who wants to also argue his side. What's not OK is being a complete dick to those using any kind of technology if it works for them.
Suggestions of solutions that might fit their needs better are OK, but you damn well better make sure you truly understand their needs and you need to know how to take "no" as an answer. As someone who works in IT and loves technology as a hobby, I used to waste untold hours getting wrapped up in this crap debating the most pointless of things online or in person. Having spent some time volunteering at a non-profit that turns 6 and 7 year old computers that a kid would label "Old crap" into perfectly usable systems for those without a computer has given me a reality check. When it comes down to your love of Linux, Windows, OS X, iOS vs Android, whatever - 99% of the rest of us just don't care. It's ok to be passionate about something you love, but don't be a dick to everyone else. We use what works to achieve the desired result.
