Tomaeto .... Tomaato ... Tomato

The common phenomenon - the "X effect" traces its origin back to olden day spell-checkers, wherein, when you type the word "cooperation", it spell checks to X. The reason being that, olden day computers had only the hyphenated form (co-operation) in their dictionary. This spelling review to X was quite a highlight in the early days of computing, when Apple was the pioneer in the field.

Modern examples include:

definately -> defiantly
voldemort -> voltmeter
DeMeco Ryans -> demerol :D

ID X.
