I have had my Zune for about a week now and I still have my ipod video nano. I will first say that I love the device. The screen, controls, and sound are fantastic.
The software however is absolutely HORRIBLE! If you ever used Itunes and liked it, not necessarily loved, but liked you will be disappointed. I like itunes and can tolerate it idiosyncrasies. I can download podcasts from the new Zune software, but when I sync to it and it takes 30 minutes to an hour to convert the video podcasts before I can take it with me is ridiculous. The Zune 30 really needs to have the added support of more codecs. Through itunes I can download, sync and be on my way in less than 5 minutes.
The lack of video support on this device with a screen this size is two massive black eyes for it. Seriously, why do I need to convert the video that I download through the Zune Marketplace? This is unacceptable that I have to wait to FOREVER for it to finish so that I can go.
I love the device, music is great on it, but man it chaps my arse with the video conversion BS. I am seriously considering selling it and giving up the screen size and going to an Ipod 80gb, but I know the moment I do their will be an update that fixes this and I will regret it.
