It all depends on what your needs are. if you are looking for video playback along with mp3 then apple is certainly not for you.its 65 k screen is crappy and videos appears washed out.When it comes to video playback nothing beats zen vision w.it can play alomst all know formats.Also if you want to use Fm radio, then ipod is not for you.
Here are the pros and cons pf the players you want:-
Toshiba Gigabeat S:-
if you are after music then Toshiba Gigabeat S is a better option and beats the ipod easily in audio quality and screen size.Also file navigation is very easy even better than the ipod.offers FM radio support. Downside:-Battery life sucks .
creative zen vision m:- great vidoe playback,can play almost all formats. Has an incredible screen, a simple interface, better video battery life.
downside:- scratch prone , included earbuds aren't that good.I also don't like its touch-pad controller.Vision:M's touch pad isn't as good as the ipod's click wheel.Aslo it doesn't look as good as the ipod.
ipod:- Looks great.Infact only iriver clix looks better than the ipod.Better battery life. Downside:- everything else--i mean no fm support, bundled earphones are crappy,small screen size and crappy video playback....also i hate itunes.
So in the end i believe the best player would be Toshiba Gigabeat S.However this product is not sold in india and so if it ever goes kaput you will have a hard time fixing it.You will have a problem when its battery dies down.if you don't mind this,then go ahead as it offers the best audio quality among the three and is good for video playback also. if lack of support bothers you then buy the creative 30 Gb model.Ipods are overhyped and for the features they offer,they are overpriced.
But whatever you buy don't forget to buy quality earbuds for your mp3 player as these are very cheap in america compared to india.
