it tends to be the pda/phone/good camera phones that are the chunky mofo's.
K800 is good, especially if u want just a phone and a good camera. but the nokias do have the Symbian OS, and are capable of loads more than your average phone. tomtom mobile for one.
n93 is a fat b*****d, but....its got the camcorder quality video, excellent camera, sat nav on it.
if you use all 3 then it saves carting about your camcorder, digi cam, tomtom go, and phone all at once
if you dont care about any of that then something smaller would be better. im not a fan of chunky phones, but i like all the gadgets and what not so i dont mind walking around like iv got a stonk on in my pants.
hehe
