So, after looking around I am going to:
Put on the Google Now launcher
Turn off the Samsung Magazine / Flipboard thing
Set the menu etc animations to 0 or 0.5
Disable S Voice via the homekey
Update to 5.1.1 as it's been released across regions now
Disable any Samsung apps I won't use
Install Chrome Browser and MX Player Pro
Along with all my games that should make for a nice fast device no?
Been keeping an eye on just Amazon UK and they had run out the other day, today they had 3 which is now 2 with more on the way, so people are buying them, hope their isn't a rush after tomorrow otherwise the price might not drop for a while?
