Well, Android is built off the Linux kernel, so technically it's linux based
It's definitely Android, I'm working on getting a debugging bridge open to mine so that I can try to install an app or two on it. But there is a pretty good chance that an out of the box Android app wouldn't work on it, even if you managed to get it installed. Probably missing a lot of the AOSP API that the app would depend on. Probably have to write it specifically for the A&K. I could be wrong about that, but that seems to be the case to me.
mmm......I'm still going forward with purchase of AK 70 (reserved already with my dealer, to be used as pure transport to pair with either the Eclipse or the CDM, depending on my mood.. Lighter, smaller, thinner than the AK 380 cu and the AK 240. I'd like to lengthen the battery life of my cu (wasted as pure transport, assuming the USB becomes a digital-out).
