You'll love Apple's smart new "Touch Space Bar", which lets you continuously adjust the width, style and semantics of Unicode spaces from zero width, hair thin, various EM&ENs, to obesely fat, pregnant pause, breaking, non-breaking, numeric, oghamic, figure, ideographic, word, punctuation, visible, ␠ symbols, mathematical, poetic, scientific, pseudo-scientific, streaming, auto-repeat, lossless and lossy compression, deep, personal, safe, digital rights management, Mongolian vowel separators [1], etc, simply by swiping, tapping, crossing and snapping your fingers, while watching the mesmerizing colorful blinking graphical feedback provided by applications supporting the NSTouchSpaceBar API.

Microsoft also has a dog in the space race: see their "Space Characters Design Standards". [2]
