The Android port of XBMC seems to work pretty well. After installing the .apk and launching the app once so it could create its config files, I just had to add my
passwords.xml files to get the tablet talking to my Samba/MySQL back-end.
It appears that hardware decoding might not be working; standard-definition content plays just fine, but 720p x264 video stutters badly, and 1080p is hopeless. It’s still early days for XBMC on Android, so this may (hopefully!) improve with the next release.
