This whole “tablets are for consumers, PCs for creators” meme is ridiculous. Next they’ll be claiming you can’t create on paper because it doesn’t have a keyboard. Yes, they have constraints that PCs don’t have; but that doesn’t prevent creation, it just changes what you can create.
@Justin: in that comic, the guy seems to have ended up in the same place. Except with his new setup, he can actually get up and take the screen with him as a tablet. Which is, in my opinion, a major improvement and something I’ve wished for long a time, as a 12" laptop user. In fact, that’s what made me so excited about the “Touch Book”, which was a laptop/tablet hybrid, which is a model I hope will become more common from now on.
For people claiming that tablets are just too underpowered, that’s true for now, but I think that’s a shortsighted view. As the supply of fast, reliable mobile Internet increases to meet demand, the concept of “augmented capabilities” will become more and more common.
As an example, check out how the Kindle Fire can do its rendering either locally or on Amazon’s servers, dynamically. This model can be extended, allowing resources to be allocated in real time depending on the needs.
This has existed for years for e.g. programmers, who often have a much more powerful “build server” that complements their workstation, but I expect this to become much more common and transparent to the final user.
