Symbian or Windows Mobile OS

I was in a dilemma in choosing either a windows mobile or a symbian mobile. If I have to choose a Windows OS mobile then I have to sacrifice Nokia brand. I personally prefer Nokia mobiles. But most of the Nokia mobiles comes with Symbian OS. So if I have to buy a Nokia mobile then I have to go for Symbian OS. But there are many applications for Symbian OS and tehre are not many applications for Windows Mobile OS.
