Verbs for iPhone is a gorgeous new IM client that just recently hit the app store. It supports GTalk and AIM/MobileMe at the moment. I'm hoping support for more clients like Facebook chat and MSN are added in an update. What really got me hooked on Verbs is the beautiful interface. It looks like an app Apple would build natively into iOS.
Another feature I really like is the fact that it supports Cloud and Droplr file transfer services. I personally love Droplr and use it exclusively for sharing images and video. I chose it as my Pick of the Week a few weeks back. This is an added bonus for me.
I would like to see full push implemented as it currently only supports local notifications. This means you'll receive notifications only if the app is running or multitasking. If you close it from the multitasking tray, you won't receive notifications any longer. Not a huge issue for some, but may be a big one for others. If you're looking for a decent IM client that comes at a fair price, make sure you give Verbs a try and let us know what you think!
