I'm always a little cagey about leaving laptops plugged in unattended nowadays.
I converted my parents a few years back and was so happy when I could finally stop cleaning up virus and malware laden crap. Even better, when I came to visit, I wasn't scared shitless that there were any key loggers or other unpleasantry installed. Yes, I know OS X isn't malware-proof, but it "feels" less vulnerable than what they had. The OS is set to automatically update along with their apps and everything is automagically backed up with Time Machine. My Dad still likes to play games in Windows; running Boot Camp and Deep Freeze keeps things happy there and when they want to surf, they just boot back into OS X.
To those saying keeping email forever is hoarding: not if it's done right. You'd be surprised how useful it is to go back and find an email from four years ago.
People don't drop these courses, because they don't remember them and/or don't think about them. The same goes for "hybrid" online courses, where you still spend some class time in a physical classroom. You're not getting enough cues to actually realize you're doing poorly. The instructor is also poorly interfaced with the class that they don't match a student's online progress with their physical presence.
Maybe working on your day's assignment in your PJs at 3 a.m. appeals to you. I still want to see and talk to the instructor. I need that "meat space" interaction.
Don't get me started on taking attendance in college courses, though...
Fundamentally, I think this is why we need some form of authentication that "only you know," but everyone can verify/authenticate against. Most places -foolishly- usually social security numbers here in the 'states. I think that's a terrible idea as the protections surrounding them are incredibly weak. I was going to suggest this fellow have some sort of PGP/GPG setup, but if the criminals got into his email, they'd probably have his passphrase(s) and key(s), too.
