Droid charge is a well built phone. Even though Samsung deviated from dev board specs. It has no USB otg capabilities. Regardless, its more durable than the s2, but I'd pick the s2 for daily use over the charge for screen and processor speed. The Exynos is a bad mamma mamma processor. Nothing currently is better except OMAP 4460 on the Galaxy Nexus.

 

Oh... you said x2. Yeah. Switch to charge. Its a better all-around device.
