My point being is that the app should have the versatility to be used on the Go with out being having to log into the website. It also has to be so Dynamic that it literally Trashes all other facebook apps in existence.

Look at it this way, Not all countries have good 3G or HSDPA broadband, more over the fact that all those packages are insanely expensive and will kill you if you do not have the right data plan for your phone (happened to me before). By having a widget such widget will be:
1.Alot faster.
2.Cheaper definitely.
3. Easy to use on the go.
