Same for me. I wanted a simple app like Google notes however a bit more suited for long form texts. Simplenote works brilliantly for me. I gave Evernote a try, however that seems to be more suited towards power users who take a lot of notes and want to capture notes in mixed medium - text, photos etc.

Also, since Simplenote is from Automatic, I am less worried about shown any advertisements or product changing radically.
