The higher res screens, won't be happening that soon.. Maybe 640x480 at best or something, not UXGA resolution. OLED is the answer to that, and its not in '04. Sure there may be some ARMv5 1ghz processors available then, but these cpus are available even now. The reason they're not in PDA's? two issues, cost, and power consumption. Polomer battery technology will help there, but again, not in '04 at any price point we can afford. As for faster memory and/or more peripherals, its just a matter it being too costly and too much power consumption.
The price of PDA's is being driven downwards, and unlike other commodity markets the volumes are just not there. Any real push these big companies are making is in the area of cellphone technology. And while this 'vision' seems to incorporate some of that, I don't think there will be a PPC convergence device on the market, or very popular in '04.
So just because the stuff is available, it doesn't mean it will make its way into a particular device.. Going back over the last 3 years, there have been SO many cool chips/technologies developed, and even many cool refernce designs (IBM's linux in a wristwatch for example).. Blame the sucky economy or lack of demand, but its just not moving as fast as PC stuff..
Hopefully at some point thing will ramp up, like they did around the time of the 486 for pc's, and we'll start seeing cooler stuff in the PDA market. For now I think we'll have to look at the PDA's smaller and less useful cousin, the cellphone for that.
