BGR is reporting some interesting ZuneHD specs, some of which look pretty solid. Notably, it would be the first mainstream device with NVIDIA's Tegra ARM chips that are supposed to blaze. Also, a large, touch OLED screen would be a first in a mainstream electronics device as well. We'll have to wait until August to see if Apple will match these so far imaginary specs.
