try it and see. it's not nearly as functional as the apps on other platforms. the best apps on other platforms aren't necessarily the official facebook apps, either. for example the webOS app is made by Palm, and it's really good. the good iphone app isn't made by facebook, either.
i guess the point is no developer has really taken the time to make a well rounded and polished app for facebook like is available on the other platforms. the closest we have, IMHO, is Bloo. the dev made it open source so it can only get better, as long as people take it up and make it better.
The lack of notifications is what bothers me. My Blackberry had this and it was great - Facebook notifications didn't clog up my inbox and were easily ignorable when I was at work. That issue is a major loss of functionality to me.
I use the native app for almost everything, but keep Bloo 1.5 running for chat (personally I think Bloo mostly sucks, but it does do a couple things I like such as chat and tagging people in photos). It's too bad Bloo isn't better than it is, since it has a lot of potential.
I get notification in my top bar, and I'm not sure if they are from Bloo or the Native App. I think they are from the native app...at least they have the same icon as the Native App notifications (that little "billboard sign" thing)
Here is one of the main reasons right now!!!!!!
