I’ve been trying out Prism, the platform for running Web Applications directly on the Desktop.
I’ve been looking for something like this, my Firefox installation gets too crowded with plugins, leaking memory and decreasing responsiveness. A platform like Prism allows me to create a trimmed down Firefox for Gmail, Netvibes, and other Web-applications.
The trouble is that while it is low on the features, it is not so much on the resource usage. Moments after starting Netvibes, my RAM touched 50Mb, consistent with what a resource / plugin / feature intensive Firefox would consume.
Anyway this explanation sums it all pretty well.
