I pre-ordered a Zune HD, should be on my doorsteps in a couple hours.
I have an iPhone 3GS so I am not giving up on anything on the Apple side. I also have my iPod 5.5G Video that I use daily. I have owned an iPod Touch (first gen, before the iPhone) and a couple Nano's and a shuffle.
I like the looks and feature set of the Zune, especially the Zune Pass, which I have signed up for. I like the idea of the subscription plan with "keep 10" per month. Some people don't like that idea, and that is okay. To each his own.
The Zune HD looks promising. It is starting out with minimal apps, but Apple did the same thing with the first gen iPhone/iPod Touch. So there is potential for this to be a cool device. I don't think that the web browser on the Zune will ever compete with mobile Safari, but that isn't why I wanted a Zune anyway. It will never out do Apple's success but I think that competition is good. Look at the iPod Touch's announcement on 9/9/09. Nothing new because nothing is competing with it at the moment.
I bought the Zune HD primarily for the Zune Pass. I have my Macbook Pro and iPhone combo. The iPhone will go with me everywhere and the Zune will likely stay in the car. I got sick of my Sirius Subscription playing the same music over and over an over, so I got the Zune with Zune Pass.
HD Radio isn't a compelling feature for me because there are no HD stations in my area. HD Video out is a neat feature but I'll probably never use it. It does suck that they don't offer Zune software for the Mac. As it stands now, I use my daughters laptop for my Zune. I could use my bootcamp but don't want to use up the Hard Drive space or more media.
That is how I am going to use it. Others are fan boys who just bought it because they like MS. Others are Apple fans and won't buy it just because it is a MS product. Me personally could care less who makes a gadget if it is cool and I want it, I get it (if I am financially able). I think that the Zune has potential but will never outsell the iPods. Again, I still have iPods but I wanted to try the Zune Pass and the Zune HD looked like a great way to go.
Just my .02
