I can't explain words that marketing places on literature.
Your PDA vendor/support must tell you what maximums you can use. But the largest consumer SD Card out there is 1GB and you can get disk drives in CF form.
bob, what does that mean exactly? i know type I and type II have different physical qualities...ones thicker than the other...but what does that mean for me when buying more memory. I checked the websites, but i'm not sure if sandisk or lexar have that kind of cf. im thinking about purchasing the ipaq hx4705. it also has an sd card slot for expansion, but sd cards tend to have smaller sizes memory wise. what do you suggest? are there 2gb cf type II cards?
