I don't know if others agree but I feel that the need for apps for web sites such as facebook is much diminished on a phone like the droid. The screen is such high resolution and the browser so good (including dolphin) that I have no problem and in fact prefer viewing all web pages through their native website rather than using a special phone version.
I use the full web page for igoogle, likewise amazon, facebook, flickr etc. etc. Even the need for zooming in and out (like pinch zoom) is not as important as on other phones even the iphone with it's lower res screen. I have dolphin browser and it's great however I rarely need the pinch zoom feature since I can read fairly well most websites at normal size. On the iphone I remember I always had to keep zooming in and out and scrolling around.
The Droid app is ok. What bugs me is the notification updates. When a FB notification come-in on the BB, it come into the message center. You could click on it and the notification was opened in the BB app. On the droid, my notifications are opening on the browser FB mobile. If I have an app for something it would be nice if you could do it all through the app.
This is an early release, and is going to be buggy. They left things out, i assume because they couldn't release them correctly. But one look at the status updates screen should show you why the app is better/cleaner. The web might be better for now, but it wont be in the long run, don't give up on it.
I actually feel as though the Android facebook back is 100% usable and is very similar to the blackberry version. I was merely stating that I don't think a "true" facebook experience will ever be captured on a handheld device, and therefore the mobile website was plenty-enough to satisfy my facebook needs.
That being said, I do still have the facebook app, and with widget integration, it is a great step forward and has the potential to change my mind.
