Android :: How To Decide Between Galaxy-s Vs N900?

I am planning to buy a High End phone. Though my Basic requirement is mostly Emailing, IM and Web Browsing. My prime concern is whenever I visit a website the viewing has to be clear and comfortably big. So I am looking out for a phone with a decent screen. Now I have shortlisted two phones the Nokia N900 and the Samsung Galaxy S-i9000. I know that the SGS comes with an Amoled Screen, which supports 16 Million colors but frankly speaking a lot of people have been saying this to me besides the big, vibrant screen the SGS offers there is nothing special about it. Still running Android 2.1. Ok Offers Multi-touch screen, Pinch to Zoom ease and all. But frankly it cannot be the only deciding factor atleast not for me. Android Apps have reached to a staggering number but while everyone is happy about the numbers a lot remains to be desired on how much of those Apps are really useful. Though Multi-Tasking is also there on the SGS, the quality and the experience is Horrible is what I have heard from initial feedback, it keeps killing most of the apps in the background when you run a website on it.
