Check the full post and comments therein for a snapshot of how the Notes value proposition is still subjective/situational, in many respects...
Every product has a core strength. It's not necessarily the unique selling point since that is created by marketing. I mean the core strength that was built by engineering a great idea. Let's make some examples:
- The (Palm-)Pilot was the first no-nonsense mobile device that synced contacts, calendar, tasks and notes with your desktop.
- The AK-47 is a simple, easy to build submachine-gun, that never jams.
- The BlackBerry is a worry-free mobile email device.
So what is Notes? What does it do better than anything else? Don't dilute the message by claiming everything but the kitchen sink.
