OK, folks. I don't expect that I'll ever need all of the bells and whistles that the Zire 31 offers. I will probably never have so many appointments or contacts that I'm seriously pushing the limits of the Zire 21's 8Mb of storage. I already have an iPod mini and so I don't really need an additional MP3 player. Am I really going to miss the color screen, or the 16Mb of RAM? Someone talk some sense into me.
