the axim is the best, but then again every ppc has its downflaws
the built in calender is great but you can alweays download better, i am always playing old nes games with my axim, it works great with and without sound, battery life is long compared to most other pda's but if that worries you u can always buy another battery.
Movies work great on the axim and if you compress them right
http://www.aximsite.com/boards/showt...threadid=3692, they should run great, but you can always tweak the settings to get the file size lower or higher, so the quality is better or worse.
lets see what else, for mp3 (u'll probobly want to get u get a storage card for this and the movies) windows media player is built in and works fine, but you can also download many other great players right here at aximisite. the quality is very good however the speaker is mono only. thats the only downflaw, but your probobly going to want to get headphones anyway. as i said battery time is better than most. storing on this axim is either compactflash(cf), or secure digital(sd), the only pda that i know of that supports usb is the toshiba 7xx, which other than that and the built in wifi, is a step down from the axim or so im told, however you can get this if ur set on usb you can get this
http://www.ratocsystems.com/english/...ges/cfu1u.html but it is only usb 1.1, which is slower, also new technology will come and caompactflash hard drives and cd-rom readers may soon be available (i hope), you can always get enough memory through this set up if you want a hard drive

but all in all, i think your best bet would definately be with the axim
good luck and welcome to aximsite!
