Danm! I'm still waiting for my Android Tab to let me download 4.2.x! I'm still stuck on 4.1.1, with no updates for my device in site. If due to being more outdated in the futrue I end up either not being able to run apps, or having some Malware exploit a security hole, then f*** Android altogether! I'll experiment with completely Android as odds are, the ARM/tablet version of Ubuntu will work just fine!
