回複：PDA就是在沒有交流電源的場合用的，你要外接電源，

do you have a pda? sounds like you don't. the battary is short, most time only for 2 hrs use, even shorter with Wi-Fi on, say 1 hr. you have to use cradle charging your pda a lot, or buy a high capacity battary, but too heavy to carry around....

don't buy one with palm os, buy a pocket pc os, a lot more powerful. palm is no future!
