It's understandable. I think to be very safe on the computer people have to be really up to date on what's out there. But that's exactly my point - not everyone can do that, and it's easy to let one's guard down. Probably most people here didn't know about Java, even though it became a really big computing issue in January. I think most people just want to use their computer as a tool, but not necessarily have to spend time dealing with the actual tool (and they don't, and they get compromised).
Well, it's not like I take care of the computer in other ways as well.
I think it's just because I think it's pretty secure overall with a good browser, one antivirus, one anti-malware, a firewall, Windows security systems, and my own knowledge.
And that may cause one to not consider other things as well.
But the people who are likely to purchase a tablet are doing so because they don't want or need more control.
My desktop computer can do much more than my tablet, but I don't use it much because my tablet does pretty much everything I need to do frequently.
There are still plenty of resources available for people who have the need/want to do more.
It's not as much "do stuff" as "know what your computer does".
If a company wants to do shady stuff, then what can you do if you don't know what settings your computer has?
There's no way that companies won't try to make money off of you.
