Yep, I've only paid for a couple of apps ever and Swiftkey was one of them - head and shoulders above the standard keyboard and all the others I tried.
I also use Opera mobile for my regular browsing and for here when Tapatalk can't do it - moderator's section and viewing gifs. I also, on occasion, use Dolphin. I need to look into others.
For anti-malware I use Lookout but I've again been lazy and used that for more than a couple of years, it may not now be as good as it was so I'll need to investigate alternatives.
