I absolutely love it! You'll notice that most of my posts (with the ironic exception of this one) are from that device, and thats not an accident. I use the Nexus 10 for absolutely everything because I'm treating it as a laptop replacement during my gap year to extend the life of my undergrad laptop. I initially had an ASUS Infinity and was underwhelmed by its performance (or at least the performance I had envisioned for it before I purchased it). I knew a Nexus device would near-perfectly with its software, so as soon as the Nexus 10 came out, I knew I had to have it. I've had zero complaints about it, from its solid build quality to the speedy software performance you're enjoying on the Nexus7 (I'm sometimes still amazed how everything happens seemingly instantly). Almost got the 7, but was worried that 7" would be too close to the 4.65" screen of my GNexus.
Sorry for the tangent 🙂
