Thanks Matt.

I read about it being slower, so I was (am) a bit concerned. My gf is considering buying a Nexus 5 for little money to replace her S3, but I really don't want her to get a device that gets slow in few weeks because of Lollipop. Her S3 is, currently, so annoyingly slow it would drive me crazy. My hope is that a nexus 5 would allow her smooth usage for the entire life of lollipop, at least.
