"Ehh Run?"
Ive had mine for a month, it was grreat at first, now it deleted all of my 3000 songs i had on it, it will only add 400 back and it says error every time i try to sync it. ive had a 8gb before and the play and back button would freeze all the time. it may be my luck, or maybe zunes just suck. i never had this many problems with my ipod although i had some on occation, non to this extent

"Great Device"
I absolutely love this device. It is packed full of features and has great performance. With the latest firmware update, they have added 2 games onto the device (more games can be added by using some MS Tools).

The touch sensitive control pad makes it easy to navigate your selection, even quick movements of your finger in an up or down motion will make your selection bar move quickly, almost like a roulette wheel.

Movies are breeze to get on. I converted a number of my home movies using DVD Catalyst, and the quality was amazing on the device.

The 4 star rating is because of the quirks it has:

My only complaints are that it forces you to use the Zune Software. I would have much rather used Windows Media Player to create playlists and sync, or have the ability to copy files directly to it like a removable USB Device (my wife's Gigabeat S30 can do this function). The only thing I do like about the Zune Software, is that it makes tagging/grouping movies I've converted (I ripped my Band Of Brothers Collection, and it allowed to mark them all as being related, with episode numbers, titles, etc), as for music and playlist transfer...I still would rather have WMP

I also have noticed that the touch pad is extremly sensitive. At times, I have accidentally jumped songs, or messed with the volume not even realizing it.

An included AC Adapter would have been nice too, but the only thing included in the box is a USB cable. While it does charge quickly, this makes getting a quick recharge in an airport difficult without pulling out lots of equipment.

Battery life is ok...depending on what you are doing...for music, it'll last you a while, but for movies, I was only able to watch 1 1/2 movies before it powered off.

Overall, even with it's quirks, I would 100% recommend this device who is looking for a feature loaded mp3 player.

"Buy something else!"
I purchased an 80Gig Zune in September 2008. I paid 239.00 here at Amazon, so I don't know where they are getting the 500.00 price tag. Anyway, I owned it for two months, and was generally happy with it. The interface software is difficult to work with. You would think Microsft, the makers of Office, could come up with something more friendly than their Zuneware.
The hard drive froze up and failed completely after 2 months. It takes about 6 weeks to get it to the factory, get it fixed, and returned. This is lost warranty time.
I replaced it with a 120Gig Zune. The hard drive on this one failed within four hours of turning it on. I sent it back.
I'm done with Zune. Microsoft cannot make a reliable product or decent software for it.

"AWSOME Devise!!"
I love this Zune 80. Its a awsome devise. LOTS of storage. Awsome LCD screen. Big one to. Awsome Premium Earbuds. If it doesn't come with them send it back. The ear buds make the orignail ear bugs sound like its from the past. Over all I love this Zune. I also bought a 120 Zune too and I am keeping them both. Don't pay 400+ for this or buy a USED one cuz you never know what your gonna get. Sellers LIE ALOT!! I know I have delt with plenty of them on Amazon.

"Piece of s**t"
I think the problem was the crap software. It worked fine for months then I upgraded the software to version 3 and it froze up and never worked again. I eventually threw it away because it would never respond again. Completely dead. Over $200 wasted on this thing because of crap software from Microsoft. Thanks for destroying my Zune you idiots. I'll never buy another one.
