I have been waiting for Android and IOS alternative for a very long
time. At last ubuntu came up with ubuntu touch and it looks very very
promising (except for Mir DS you should have gone with Wayland). Porting
guide was very good starting point but all of sudden you released
flipped images and all the existing docs become useless now we don't
have a good starting point or any kind of help. Many people asking
question about porting in this mailing list are not answered. pull
together guys if ubuntu fails then we are stuck with Android for at
least next 5 years.
