Personally, I don't like dollar bills much because new ones stick together and old ones get raggedy and don't like to stack. The dollar coin doesn't weigh nearly as much as it once did. Before 1979, it was HUGE! (Does anybody remember the Eisenhower dollar?) Also, the dollar coin in its current size and weight has been out for 25 years, so a lot more vending machines accept them than you might realize (not just the ones that have that sticker on the front).
Am I biased? Perhaps. Inexorable? Hardly! I also prefer the metric system, but I haven't jumped full-off into it yet because I'm still surrounded by people who use the American system (I can no longer call it English since they, too, have abolished it). Likewise, I'm not going to stop accepting the dollar bill just because I don't like it. It's money! I like that part of it. But I'm either going to pass it off on my employer's till or trade it in at the bank.
