You find WMA more useful than audible? Audible is audible.com's proprietary format for their various audio periodicals such as the NYT and WSJ, as well as their excellent and ever growing audiobook library. Unless I'm mistaken, you're comparing Apples to oranges (ahem). Audible is fully supported on the iPod. I'm a subscriber and love the service.
Incidentally, if the rumor mill is right, the iPod will soon support AAC, the MP4 standard. As you likely know, Macs support this now via Quicktime 6 Pro.
PodWorks is an iPod-only routine, so I assume you made a little typo when you said it supports Zen - Zen transfers. And, BTW, PodWorks handles batch transfers easily. One can transfer the entire 20 GB contents of one iPod to another in a matter of minutes. It also supports drag and drop directly to and from the finder or multiple iPods. This is the kind of elegance that Apple fans have always been willing to pay a premium for.
I'm glad to learn that the Zen has browse features similar to the iPod. But, I read somewhere that the Zen can only access its music via playlists. If true, I would consider this a very major shortcoming. The iPod can play any selection on the fly. For example, within a very few seconds one can find and select any song, an entire album or the complete works of any artist or composer--all without a playlist. In fact, I rarely use playlists at all.
It's true that the Zen only weighs two ounces more than the iPod. Of course, stated another way, this also represents a 26 percent increase in weight. Not so much, except when specifically dealing with miniaturized equipment as we are here.
It's also true that the Zen has both USB and Firewire ports. The iPod has only the latter, but why would anyone use USB when Firewire is available? For sometime now, all Macs--even the cheapest--have included Firewire. Just for the record, how many days
would it take to transfer 20 GB over USB?
The Zen has a more elaborate remote than does the iPod. But then the iPod often doesn't need a remote at all. I carry mine in a case inside my shirt pocket. All controls can easily be operated through the fabric. The scroll wheel is touch sensitive like the trackpad of a laptop, and all other controls are push-to-operate. I have never bothered to unwrap my remote.
I'm sure the Zen is a fine machine and I look forward to checking it out. Is it true that it comes with a 90-day warranty? This was the case with the original iPod, but they now have one year. I purchased the first one the day they came out from CompUSA and was able to get a two-year replacement warranty for $29. I assume the same can be done with the Zen.
At any rate, Zen or iPod, isn't it terrific to be able to run around with about 400 albums in one's pocket?
