As a owner of a novena laptop, I'm always happy to see other OSHW laptops.
Though the thing with the TERES-I is, it just doesn't seem to be made for daily use. There is only 1GB of RAM, no (m)SATA, the eMMC is rather small and the only expansion seems to be a uSD card. Even something like the eMMC modules the people from hardkernel put on their boards would up the usability quite a bit. I'd love to like it, but I'll have to continue searching for something 64Bit ARM I can just toss into my backpack to play and tinker with on the go.
