Have you used the Silk browser? It performs like a pig. Turning off "Silk" is the only way to use it. Even then, it is substandard, in my opinion. If I have my Kindle Fire in my hands and need to look something up online I will usually put it down and reach for my iPhone on the nightstand. It is better than nothing on a device I use primarily for reading books, but I would steer clear of any phone running it.
