I think its one of the most brilliant app designs yet... as for the missing functions mentioned. Most users do not care for those things and the look and feel of the news feed is the most important. They will most likely be added soon though, and will be fully functional in apollo if I had to guess. For now the banner images is just awesome to look at while scrolling the news feed.
Thumbs up here, haven't seen a more attractive way to use facebook yet!

Features like "liking" an individual post, uploading photos to friend's walls, checking in with friends, among a host of other features are indeed important to most who use Facebook. If it does not support the features people who use Facebook want, then it does not matter how pretty you think it is. Personally I think it looks outdated since it does not support Timeline.
Also there is no reason to have to wait for "Apollo" to get these needed features that are missing. I am tired of hearing "Once Apollo releases all WP worries will be gone." I heard the same bupkis about Mango. You never hear people with iPhones saying iOS 6 will be the one! Facebook can make their app work with all those features on Droid and iOS, they can do it now for WP, no need to wait for the next OS release.
