The Aeon skin was never finished. It was done to show that a skin could be hand ported from XBMC to QML, however, as merkur2k found out, there are far fewer screens in XBMC, than there are in LinuxMCE, so he ran out of stuff to use, _very_ quickly.
As for the default skin, you may want to talk to golgoj4 about this. Right now, dealing with DPI differences between devices is a bit of a challenge, and you'll probably need to change the qml for the skins to work properly. We need more people to help write skins and work through these interesting challenges.
