I'm glad to see more and more people are realizing N900 was terrible.
As much as everyone says iPhone is bad with "less features than N900", the iPhone4 has been great so far and I've really enjoyed having it.

The phone does everything it's meant to do quickly and smoothly. Email works so well (both work and personal) with easy to set up push that doesn't kill the battery as insanely fast as the N900 did. SMS loads really fast, OS runs way smoother as well. The phone is thinner and lighter as well.

Additionally, a lot of people nowadays use phones more and more not for just talking, sms or email but also to socialize via games etc. Most of my friends use iPhone which makes playing games etc with them easier.

I have loved having and iPhone ever since I got it, and I can see myself loving an Android device as well. Never again will I look at the N900 and think I missed out on anything. So thick, heavy and took much more effort to have things running smoothly.

N900 had an upper hand over maybe the 3Gs, but iPhone4 blew it out of the water (and only 6 months later). Equal to better resolution, camera is just as good as N900 (if not better) and more importantly, CAPACITIVE screen. What advantage does resistive have now. I can go snowboarding with my iPhone and still use it with gloves now (given I have the special tabs on my gloves, and it works perfectly).
