yup, iPod has got the adapter available separately now. they used to come with an adapter and dock (for "bigger" certain models).
i usually leave my iPod in the dock when i'm home and listening to it. the dock charges the iPod at the same time. so when i'm out, it is usually "nearly fully charged". but anyway, there is an indicator for the "batt life" left. if its dying charge it then... but of course when u r travelling overseas, there is concern. but u can still bring ur adapter along. (can be used for 110 or 230v) unless u joined the Survivor in Guatemala, then it is useless...
i used to be "a mild anti iPod". i felt it was overhyped then... even tho i'm a "pro Apple" person! i was using a sony MD player then. but when i go around, i have to think abt what music to bring. i need to carry a few/a lot MD disks with me. as i might want to listen to my funk or acid jazz or death metal or pantera or the soothing japanese or nepalese flute or some african drum dance thingy... imagine the no of MD disks i need with me! so i bought the iPod. the 40gig at that!!! very greedy!!! my wife asked me in mock: "Do you really need to carry around 10,000 songs with you???" i asked myself: "yeah, huhhh??? do i really need to???" hahahahhha...
ok, that's a very long grand-daddy story there. but see what suits u. some ppl go for creative bcos they are anti-Apple, anti-iPod, pro-Singapore brands or want to be cool-for-bashing-iPod-coz-cool-wannabes-uses-iPod. or u just believe the "other brands" has got better functions that suits u, or its better priced, or its cooler-as-less-people-are-using-them.
me, i'm happy with my iPod of 1.5yrs. its been good to me so far, even though its got the scars and scratches on its back because of my mistreatment!
p.s. do i really need to carry around 10,000 songs with me??? not at the moment. the last time i checked, i'm carrying 7184 songs with me! hehehehehh...
