BGR is reporting some interesting ZuneHD specs, some of which look pretty solid. Notably, the first mainstream device with NVIDIA's Tegra ARM chips that are supposed to blaze. Also, a 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.
