I'd much prefer AMOLED LPM notifications as per N9 (increases "glanceability" if I were to go all Marko Ahtisaari). And JollaHQ just retweeted someone asking for LPM - which is mildly promising I guess - they're still sourcing the best screen components aren't they? I suppose an RGB LED would be a good fallback if they really couldn't source an LPM-capable screen component.
