The fact that the iPhad is so very limited–no multi-tasking as one example–and locked into the Apple straitjacket could be an advantage for naive and/or stupid users who would otherwise be more prone to fall prey to sophisticated phishing/malware attacks. After all, since it won’t multi-task, stupid users can’t infest it with keyloggers that run in the background.
So there you have it: a “computer” for folks who belong in Assisted Computing Sanatoriums…
I just knew I could find something to like about it!
