Frankly speaking,

If I ever have the chance, I wish I could own an Iphone and a Nexus One and a WinMo phone because I just love them all. 

All three of them have their own pros and cons. You may like it or you may not.

So, no point arguing. 

All three of them have their potentials to grow in the future so why judge so early?

Take WinMo as example, if you hate any winmo phone before the HD2, give HD2 a try and IMHO, you'll say " wow, thats different!" 

Win7 is coming, Iphone version 4 is rumored to be arriving and the still-developing Android is giving surprise every now and then. 

lets just sit back and watch the grow
