I love how Sam Adams says their widemouth can is to better enjoy the aroma, in contrast to every other beer maker, whose midemouth cans are for slamming beers quicker. I think Sam Adams is being a little disingenuous. I actually like the trend of beer in cans. I would like to see more microbrews go in that direction. The 360 can looks awesome, because you can actually get the experience of drinking beer from a glass, which is obviously the best way. I haven't seen anything like that yet, but I think it could catch on. However the churchkey can is silly and nostalgia driven, and totally impractical. If you lack a bottle opener, you can still always open a bottle (use a table, a lighter, whatever), but if you have a can of beer and no can opener, then you're in a spot. All that company is doing is setting their customers up to be super frustrated. I wouldn't call that a "creative design"; I would call it hipster nostalgia gone wrong.
