Why not OneNote? Mobile clients on every major platform, desktop clients, is simple to use, and supports nice stuff like ink support, task/meeting integration, etc...
The editor in one note is way better than Evernote, which is a constant frustration with anything even remotely complicated like a checklist or numbered list. It's too bad they don't have an osx client.
Can I use it on my Android phone and sync the notes to my Windows machine and my iPad?
