I wonder why it took them so long to release this. Given how picky they are with who they hire, and the sheer number of engineers they got, why did it take them over a year to come up with such an essential product - a Facebook app for the most popular tablet device?
I'm also going to say that their iPhone app leaves a lot to be desired. Many features are missing, like inability to edit/delete posts, picture abilities and so on. On the non-mobile side, their API is infamously bad. Without wanting to sound negative about them, I do wonder why they hire so many "top software engineers" and what they have those guys working on.
