Tablets ARE PCs

With talk of a "post-PC" era, the role and understanding of tablets has become a key requirement not only for device manufacturers, which face significant potential disruption of their markets, but for application providers, access providers and others in the ecosystem.

In some ways, the tablet represents a clear new appliance category. In other ways, it also displaces the use of PCs. But there remains some uncertaintly about whether the tablet is a "mobile" device or is primarily an "untethered" device. 

In truth, the tablet is a mix of both. Sometimes it will be used as a "mobile" device, carried by a user outside the home, used outside the home and on a mobile network connection. Most of the time, though, it is used inside the home or office in "untethered" mode. 

That leads some to note, not without justification, that a tablet is simply the latest form factor for a PC. Some might say the tablet is why "netbook" demand has collapsed, for example.
