The recent Chrome Beta for Android update was notable for including password and form sync, but it turns out there is another feature lurking beneath the surface, and it's potentially a big deal. Google has built in a data compression proxy for Chrome that can reduce bandwidth usage by up to 50% on mobile networks. You'll have to do a little digging through the Chrome flags, but it's relatively easy to switch to the fast lane.
Just type chrome://flags into the address bar and enable the Experimental Data Compression Proxy. When that's done, all HTTP traffic will be routed through Google's SPDY servers where pages will be optimized for Chrome.
