We've been looking for a dashboard for our engineering group to get some better real-time visibility into the health of our systems (been weighing internal run and hosted solutions). That said, we have a massive amount of data coming in we'd like to track and I couldn't find anything about volume, data-rate or event-rate limits/pricing. However, part of the $29 plan info is obscured by the signup button, so it may just be hidden (Android device). On only a mildly related note, I only get a pleasant wood panel background on a dev account sand the demo on the same device, no menu, no widgets, nothing.
