Unlike desktops and notebooks, you won't generally find PDAs that have bragging rights for awesome video chips. The best Pocket PC performers in the graphics department are the Toshiba e805 (which has 2 megs of graphics memory rather than the more common 384k), and the iPAQ 2215 and ASUS A620 which lead on graphics benchmarks.
hmm thats too bad. is there any information about the graph specs on the asus a730??
