Vox on Nokia N Series

I have been playing around (and collecting of-course) with many mobile devices since the last four years. Started off with a Nokia 9500 Communicator. Then began my craze and collection. Bought all of Nokia E series, moved on to Nokia N series (N 76, N80, N95 8GB). My craze is not limited to Nokia only. Got a range of HP, HTC, Palm and Asus windows mobile devices (2003, wm5 and wm6), and of-course, an iPhone and a Blackberry (8700g). I thought I had studied all on & off-line applications on those devices. But...

I just bought the Nokia N95 and found the "online services", within which - VOX. I don't know, since there are so many applications similar to VOX, but this (VOX) seems different. Let me use it a few more days then I would know what exactly sets it apart from the crowd (if at all) 

You guys and gals got any other ideas? I am talking of mobile based support. Is it better than Facebook or Yahoo Go (Flickr) or Radar or Opera Mini (Opera Community), etc, etc?
