iPod,MP4,MP5 Players quality?

You are asking for too much... here are my opinions on main BRANDS (each have several modals- each one might have several generations......):

Sansa Clip / Sansa Fuze - the simplest players of the group, excellent value for money, long battery lasting, VERY good sound quality, durable (to falls), small capacity compairing to others (expand up to 32 GB).

I pod touch - expensive in terms of "just a music/ video player"- used more like a PDA (including WiFi surfing), sound volume is too low in my opinion but good quality VERY good video quality (big screen), very fragile due to slimness (and of coures- touch screen), long battery use.

2nd gen:

I pod nano / classic / shuffle - expensive but with good sound quality, long battery use. the nano and the classic have good video quality but small screen.

Archos / Cowon players - expensive (but less than Apple), touch screen (in some), thicker then ipod touch (bigger storge space and bigger screen than then Apple's touch!), long battery use (but less then ipod touch I think), like a PDA (WiFi surfing in most modals), good sound and video quality (big screen).

Archos 605:

* You can treat yourself by choosing an older modal of a premium player- I pod touch for example- not much of a difference between the 2 and 3 gen, the 4th has a camera and "face time" but do you really need it? (it is also the slimest and most fragile out of the four).
