Last.fm is rocking on various mobile operating systems
The most recent Last.fm client comes to S60 devices as the Mobbler application that is available now for free. I just installed it this morning on a Nokia E71 and it works like a champ, except that you cannot yet love or ban tracks on the mobile client.
On the Nokia Internet Tablet, I have the excellent Canola application loaded up with the Last.fm add-in. This client looks great on the large display of the N810 and is my preferred listening setup at home with the N810 propped on its stand and connected via WiFi. I also just went to log into my Yahoo! Music subscription and was presented with the option to transition to Rhapsody where my remaining year of subscription service was transferred over seamlessly. There is a native Rhapsody client for the Nokia Internet Tablets so I have a couple of ways to stream music on this device.
There is also a Last.fm client for Windows Mobile that I am now going to install on the HTC Touch Diamond and give it a try.
The capability on S60, Windows Mobile, and the Nokia Internet Tablets that will have me using these more than the iPhone is the ability to surf, check and respond to email, and run other applications while listening to music.
