as per title, i'm exploring the avenue of a new audio/pmp device
 
I currently have an iphone4 with fiio e11 and sennheiser hd25 1 ii's
 
I find there are positives and negatives to having the iphone as an all in one device and have no objection to getting 2 seperate devices (pmp/phone) if need's be.
 
I have a liste of needs/requirements as follows:
 
1) as great a sound quality as possible
2) expandle memory by sd/micro sd
3) very good colour screen of approx 3.5 inches or so
4) great battery life
5) touchscreen
6) wifi
 
having read a fair few threads and researched a little, i'm kind of angling toward these:
 
Cowon J3 - don't think this has wifi? - £160 in the uk
Cowon Z2 - seems to tick all the boxes - £260 in the uk
Cowon A5 - seems to tick boxes, similar price to Z2
 
Creative Zune HD
Creative Egg ii
 
Budget, is ideally around £250 absolute tops, and it would be at the top end
 
Any suggestions, input or ideas welcomed and thanked for in advance
