So to read about the new Android version in a general way go here;
The idea is that this is going to be a game changer in regards to latency and there will soon be a judment out on that I am sure.
What is said is 30 ms and maybe the other important part is that now it will be able to hook up USB soundcards / keyboards etc directly without special solutions.
Other news is that there will be new Nexus devices coming which is to be expected but think that the greatest news is that Nexus 4 will be Lollipopped!
This is of course great news for people that do have a Nexus 4 but as there will be a Nexus 6 out it will be possible to get a Nexus 4 and Lollipop for not too much money or for free with some harassment of your mobile service provider... the tablet Nexus 7 will also be possible to upgrade.
In either case there is more information about the new Nexuses on the same page as above.
Ahhh one last thing...
Please donate some money so Musical Android can get Nexus 9!!!
Just go to the PayPal button and insert a big amount!
