1st batch of omnia really worst for their touch screen.. but for 2009 batch.. i think its really ok cos i hv been using it and no problem until now.

for iphone, yea.. its is best of touch screen phone.. coz i remember i hv read 1 benchmark for touchscreen phones and iphone is the greatest.

not bad also spec of vivaz.. since its symbian based.. it would make easier since many people already got use nokia's symbian..
