It's something you can eventually learn to not depend on but it still feels very backwards for me. Every phone I've had since like 1998 has had an led notification blinking at me when I've had a missed call, received sms, voicemail, etc. There's been times when I walked away from my desk for a few minutes, missed a call, and came back and noticed the blinking light to realize I had a missed call. If it wasn't there, there's a chance I would've never even looked at my phone for hours. That's why I'm hoping this trend of no led notification doesn't catch on. As cmdrmonkey mentioned there, devs even had to make some kernel modifications to make up for this missing feature for rooted devices of the Samsung Galaxy S.
