I came across this glass topped pool table image today and got the idea for this thread. First of all, felt is used for reasons other than looks. It is optimal for the pool balls to move around on. Not only would glass be loud and obnoxious, but it wouldn't even feel the same as playing on a normal table. The physics would all change. Seems like an absolutely horrible idea to me. So, what other products have you come across that made you think "Wow that just won't work". Not to be confused with bad products in general like a stupid exercise item. I'm talking more about variations of existing products that are changed to make them "cooler" or better looking but in the end just make them function worse.
