This looks like a great upgrade to the ever-aging MSN Messenger client currently on our Pocket PCs.
MSBLOG has the details:
"With it, you値l be able to talk to other Messenger people whether they池e using a mobile device or a PC, you値l be able to send and recieve nudges, instant messages as well as emoticons. The speeds between the PC and the Live Mobile Client are pretty fast - with about a second or two waiting times. You値l be able to transfer files from and to your mobile device, including recording a voice clip using your device microphone and send pictures with your device camera.
With the Live Mobile Client (not the final name by the way, we値l keep you posted on it), you値l be able to click on a contact with your devices buttons, and check out their contact card and Live Contacts details - so you値l be able to check out whether they致e updated their blog and also pick up their contact details from your handset. You値l be able to subscribe to RSS feeds and view the latest updated feed, as well as being able to access your Space and email via Windows Live Mail (Mobile). It痴 really cool from what Phil showed us, and is expected only to run on Windows Mobile 5 devices, and we should be able to see it arriving in beta within the next few weeks
