Exploring the use of iPads and mobile devices in education.

My school is going to outfit our grade level (grade 2) with a 1:2 set of iPads, which we hope will then become 1:1 in the next year or so. I use Voicethread as an ePortfolio tool to gather so much work and reflection and feedback on the students' work. Is there a tool that I can use on the iPad that is comparable?
