A tablet is a PC. Especially as x86 processors start taking over arm processors.
Just because it doesn't sit in a big box doesn't mean it's a different class of system. The difference is really the openness of the platform, comparing something like iOS to Win 8 pro.
That said, many tablets are basically what we would have thought of as PCs before. Consider something like the Samsung 500T or similar, or thinkpad helix. Components are small and cheap enough that they can be packed behind the LCD, and you have essentially a laptop that doesn't need it's keyboard.
Will iPads take over PCs? No. They are too limited, not because of hardware, but because of OS limitations. Will tablets take their place though? Quite possibly. The portability is quite handy. That I can dock a tablet with a keyboard and have a normal PC experience, but have it portable when I need it is a selling feature.
The obvious cavaet is that a limited OS is fine as long as the majority of data is cloud based. In that case even development can be done on a closed platform, and the tablet becomes something more akin to a monitor or keyboard. More of a peripheral than a computing device. We might get to that point, but that's not the cause of the current trend.
