recommendations on pocket sized media tablet?

which media tablet do you recommend?
some examples: ipod touch, archos 43.
these are the specs that are important to me:

- good audio quality and when over ear headphones still be able to hear loud.
- hd video playback
- fits in pocket but still acceptable to watch videos on, roughly ipod touch size.
- either very large hard drive: 64GB + or, which i prefer, removable sd card or something like that.
- WiFi
- proper internet browsing capabilities
- not forced to use a software like itunes to use, like the ipod.
- touch screen, prefer multi touch
- removable battery would be nice but not a must.
- cool apps are nice but i know that most gadget that dont use itunes dont have good ones.

i think thats all, if you recommend me one and you find other cool features or specs of that gadget mention them too.
i kinda dont want to buy something from apple, but i realize the ipod touch is pretty cool. i thought about the archos 43 but i first want to know if theirs nothing else out there, and is the archos 43 the latest model? if yes anyone know when a new one is coming out?

how does the archos 43 sound quality compare to the Sony Network Walkman NW-HD5?
