I just bought a new phone. A HTC Titan, with Windows Phone 7.5. I'm excited to try WP7. Previously I've had an Android phone (Nexus One), but I think WP7 might have potential.
After playing with it yesterday I think the look and feel is really nice. One big drawback though. I opened up the Zune player and was happy to find a "podcasts" option, since this is a big part of what I use my phone for.
Big was my disappointment when I saw the message "Connect to your computer to synchronise podcasts."(!) when selecting the option. I haven't connected my phone to my computer to get podcasts since I owned a Ipod Touch 3 or 4 years ago. On my N1 I could subscribe to and automatically download podcasts onto my phone.
Huge potential for improvement here Microsoft.
Until they get it fixed I'm trying out Podcasts! app from Meltingpot software.
