Double-Trinity my comment was addressed to no-one imparticular...I was just trying to make the point that some of the dream specs being given are more inline with a handtop than a pda...take a look at the specs for the up and coming Flipstart as suggested by tmn72...

Flipstart handtop specs
...now compare to the wish lists...
okay the flipstart doesn't have a touch screen but other handtops do as well as different form factors...thought the price tags still burns a hole in the pockets ;-)
...Double-Trinity unfortunately you need that space around the screen...if you've got an old pda hanging around take it apart and you'll see little of that space is wasted...you'll also run into the problem of reduced battery time with increased screen size...as well as the question of how comfortably it fits in your hand...
Looking at these specs you can see the lines between the 2 blurring...kind of like the line between a smartphone and pda...gotta wonder which will kill the pda off...my money is on the handtop...people want greater speed, bigger screens, more storage, to be able to run their existing applications on their mobile technology...
BTW don't get me wrong I love my Ax and I'd love to have a 4"plus screen, increased CPU speed, USB port, increased memory/internal storage, more functional D pad/buttons, better compatibility with desktop programs and improvements in battery life...all in the form factor of a pda...but most of all I'd like to see better batter life preferably without the additional thickness...
I too have a dream pda...all the usual standard increase in memory etc but I'd like to see the LCD screen replaced with an OLED screen...this would eliminate the need for a back light and as OLED can be made into thin plastic you not only reduce power consumption but also weight...infact I'd like to go one step further and think of FOLED (flexible organic light emitting device) screens (think the wrist screens in the film 'red planet')...so why not a pda with a 4" FOLED screed, want an extra inch to read that spreadsheet...just pull out the sides to unroll the screen...
I'd also like to see a change in battery technology...instead of the traditional lithium ion battery how about a methanol fuel cell...like the one under development by Toshiba...running low on power well no need to recharge your battery for 5hours just add a few drops methanol/water mix into your fuel cell...

Toshiba fuel cell info
...okay so the FOLED and fuel cell technology is still some way off but what possibilities they could bring...then of course there's quantum computing ;-)
