Have just had the update to 5.1.1. One thing I noticed is that multitasking is working properly now - if you've had internet open and you go back to it it doesn't reload, just resumes at same place on the page you were at. Same with other apps eg Kindle opens immediately where you left off. But if you open Chrome and then try to go back to any app they all re-load!
Avoid Chrome and your multi tasking I'd do much smoother
