So far I have been pretty happy with Prism (which is a beta) but there have been some issue with it that have been bugging me and still have me looking for a solution.
One of the great things about Prism is the low memory footprint but after prolonged usage (typically 2 hours or more) the CPU usage climbs up and ends up sucking all my CPU’s resources.
The other issue is that the keyboard ceases to function in some flash based web applications such as the recording interface for BlogTV, which of course make the chat room useless to me (this may not be Prisms fault but I’ve only experienced the problem in Prism).
Overall prism is a great application, but until the CPU usage and keyboard issues make it difficult for me to recommend it as a good solution. Hopefully these things will be addressed in future releases.
