I would trade it in for sure if it had removable storage. I use the Infinity as a media consumption device, and for travel I would like to keep the SD card slot to store movies and music. 32GB Nexus 10 might e good enough for me, but it would be cutting it close.
Forward-facing speakers is tempting. Also, factor in IO issues that I seem to experience and I have considered swapping (selling the Infinity) and buying the Nexus.
