I haven't really used a Windows computer much* in the past 10 years but now have a Surface Pro 3 and thought I might end up using it on trips when I want a tablet with me. My hope is that I can successfully install Ubuntu on it in the future and maybe someone can figure out how to get the Type Keyboard working with Ubuntu. For now, I'll probably be sticking to Windows so I need software advice.
What is the best/fastest/least buggy...
1) Virus Scan (I assume I will need one of these). I am leaning towards Avast or Sophos right now.
2) Pdf reader - Chrome reader it ok but it would be nice to have one not tied to the browser. I tried Sumatra but it is a little slower than I would like. On OS X, I usually use Skim or Preview.
3) Latex and general editor to edit html, python, etc.
I'm sure I'll think of some more soon.
*I have used a Windows Tablet PC but didn't use it for anything except Adobe Illustrator and Windows Journal. I also didn't have it connected to the internet most of the time.
