I've currently had the smartband for a little over a week now and im extreamly happy with it. Though having 4.4kitkat and blu-tooth always on is putting some strain on my old galaxy S3, so im starting to think i may aswell update to an Xperia Z2 and get to full sony experiance going on! 
Only thing is that iv had to log into the app on my galaxy with my google account, and from reading around these forums i've figured out that you xperia owners have had to sign in with your Sony Entertainment Online accounts.
So what id like to know is if there is currently a way to move furthur into the sony ecosystem and export my google lifelog data into the sony account so i can still keep my lifelog data which i really need, as iv been traveling and using the bookmark function at some great places id like to remember.
So iv gone ahead and bought the Z2 anyway since my old S3 just couldnt handle kitkat and the multi-tasking off all apps.
I havent found a solution to getting the google lifelog data to sony yet. So far iv tried to copy the Data files from the application on my old phone to the same folder on the Z2 though this didnt do anything.
I still have a backup of the lifelog application data from my old phone incase that will be needed to get the data accross.
Looking at you sony to make moving into your eco-system more welcoming here. hopefully you can still find a solution to merge both sets of data.
