I bet it's the battery.

I don't know about these things being particularly fragile -- I haven't been careful with mine and it's lasted just fine.

When you say it died this morning, you mean it was running and you were on the Internet and it just went out like a lightbulb?

Or you mean you woke up and it was dead?

I bet it was the latter, again probably the battery. But you probably need to send it back to Nokia.
