As the song and saying goes "to everything there is a season." Throughout history as man has made advancements in technology he has changed what he uses in every day life. From rocks to spears to arrows to flintlocks to rifles to machine guns to atomic weapons. From iron armor to kevlar. Times and conditions change but anyone with a lick of sense knows that there is still a time when the best thing to use for a job is that old tool in the garage. Likewise there are those who will always prefer the smell and texture and utility of leather goods. Also natural fiber clothing will always have its place. The worst thing we can do is to place those personal desires in the same catagory as religons and start a rant against someone who doesn't agree with our point of view. That said my final comment is to each his (or her) own.
