I've got 2 Zune 30s.. one for me, one for my wife.
I really like the multi-touch and Web functionality of the iPod touch, so i was planning on picking one up this year... But the same functionality that made be get a Zune 30 over an iPod Video may make me get a Zune HD - the Radio tuner.
My wife has been pining for a HD radio, so the functionality being built into this is a huge plus for both of us. Depending on the amount of storage, I'm sold. My Zune 30 is nearly full.. so anything less than 20 GBs would be painful to go down to.
I'm looking forward to the release, and final tech reviews.
