very cautious about these, anything small with tegra 3 has a tendancy to overheat. so this could turn out to be like the htc one x and other tegra3 devices. will wait for a few weeks after release to see how end users get along.
1. I think very few people have reported heat issues with the One X, I play games on mine a lot, it gets warm, but so do all recent smartphones, and thats all it does, no problems after 4 hours of GTA III for example.
2. The N7 runs at a slightly lower clock rate, and has much more structure to dissipate heat..
I think you don't need to be too cautious..
