As Explorer Edition Google Glass units started to ship out to willing participants, some official tech specs had been published on the product page. It wasn't a complete set of internals, however, and the curious among us still wanted to know more specifics about the processor and RAM in this headgear. Thanks to some clever poking around by an early Glass user, we now know that it is powered by a TI OMAP 4430 processor (you may recall the Galaxy Nexus ran a 4460), at least 682MB of RAM and is running Android 4.0.4 Ice Cream Sandwich. The folks who figured this out say they can't confirm the clock speed of that OMAP processor, nor the exact amount of RAM. With a number like 682MB, we're going to go out on a limb and say that's 1GB with some reserved by the system and hardware.
Now those aren't exactly bleeding edge specs, but when you consider that they're fitting essentially Galaxy Nexus-level specs into what is just a slightly oversized pair of glasses it's pretty impressive. As for Glass running Android 4.0, we wouldn't scoff at that much either. You have to figure that bumping up to 4.1 or 4.2 wouldn't give many tangible benefits to something with use-cases so much different from a phone or tablet.
