i have both nokia n900 and an iPhone 3GS. I bought the n900 just to see the difference between these 2. ive used the 3GS for about 6 months and ive been using the n900 for 3 months. i must say the n900 is no way near as good as the 3gs (lack of apps, need to depend on the community to develope stuff rather than actual software companies, horrible battery life, not as user friendly as the iphone, and gets even worse with PR1.2) im still going to be using the n900 but for someone who wants to change from an iphone, i will not recommend the n900. stick with the iphone!
