While the CHIP comes out looking good, it's important to note the horrendous AllWinner software stack. Last time I checked, Linux support meant using an out-of-tree sourcedump that was tied to a specific version of Linux (I think 3.0.x?). The sunxi project[1] was trying to mainline a bunch of stuff, but not sure how far that is now. In general, working with the AllWinner chip is much more of a pain if you want to do non-trivial things. Perhaps the CHIP will help improve that situation.
