Stream-based real-time architecture against a Lambda architecture

This is less of an informative post than usual. I’ll repost a question I’ve asked in Programmers Stack Exchange hoping to trigger some interesting discussion.
I’m not a real-time architectures expert, I’d like only to throw a couple of personal considerations and evaluate what others would suggest or point out.

Let’s imagine we’d like to design a real-time analytics system. Following, Lambda architecture Nathan Marz’s definition, in order to serve the data we would need a batch processing layer (i.e. Hadoop), continuously recomputing views from a dataset of all the data, and a so-called speed layer (i.e. Storm) that constantly processes a subset of the views (made by the events coming in after the last full recomputation of the batch layer).
