Don't forget about the deseret alphabet. I think it's a shame that never stuck.

Deseret us a bit too frivolous graphically, and not consistent enough.

Also, English has many pronunciation variations, and links between many words may be obvious in writing but not as much in sound (breath / breathe). English needs something more of a morphology-based writing system, not a pure phonetic representation (like Spanish).
