F2FS looks like an interesting development. The write speeds on nand-based devices are wickedly fast. Implementing F2FS on the important partitions seems to be a major way that some Samsung and Nexus devices look so good compared to other android devices. From what I have read, devs need a Linux 3.8+ kernel to implement F2FS. Any chance this can be implemented for the HD/HD+? It really could do wonders for any lag issues.
