>>"By far the biggest issue Android has is that idiots will happily install every piece of malware they can find as long as it pretends to be a free fart app"
That's what I meant when I compared it to XP and how trying to educate users just didn't work for MS which was what they tried to do for a long time. Send an attachment saying "BritneySpearsNaked.exe" and half of my colleagues back then would cheerfully infect themselves. :( That's why pretty much every Windows system these days as anti-virus built in by default and tools like SmartScreen. Microsoft gave up waiting for the kids to grow up and just went back into parent mode (for better or worse).
You can't stop people being stupid, but there's definitely room for Google to work on the same problem with Android.
