This latest tablet craze is, may I say it, just a craze.  Tablets are essentially just larger smart phones without the phones--just as the laptop has not completely replaced the desktop computer, the tablet will not completely replace laptops and desktops.  Tablets are essentially media consumption devices, they can create media but lack the real horsepower to do everything a PC can do.  I think some people, depending on what they use their PCs for may go all tablet, but to do artwork like we are doing, a more powerful PC will be needed.  I do have friends who have almost completely abandoned their PCs and laptops for their iPads--but they essentially just surf the web, watch videos, and do email on it.  Even though there are art apps for mobile devices, they have severe limitations.

Tablets have the specs that computers had 12 years ago as far as processing power.  I think they could do a limited version of Poser that would be more similar to the early editions of the program and it could be fun--but if you look at the specs of a computer you need to run Poser, Vue, or Daz Studio smoothly and do renders that won't take a week--even with a tablet version of Poser, we're a long way off from jettisoning our PCs or Macs in the 3D art world. 

I've heard rumors of a web based version of Daz Studio, but what you will be able to do with it I have no idea--or even if you will be able run it on a tablet.
