Android really makes me feel out of control. I have Galaxy Tab and to me it is a hostile device. I cannot determine what it is doing. There's a microphone and camera in there and for all I know it is recording everything around it and sending it to some third party.
Sadly, I cannot find an easy way to put another software stack/distribution on it. Hopefully this will change at some point. Ideally I would put a mix of KDE Active, MeeGo and a fully FOSS version of Android on there.
Android really has a lot of potential, but like KDE Active (linux in general) and MeeGo, there are not enough options to lock down 3rd party applications with regard to what type of communication to what servers is allowed, what hardware access, and how much memory or CPU is permitted.
Nevertheless, I use the tab a bit, but it does not feel good.
