While not the latest and greastest model from Creative, the Zen NX is still a viable choice these days. The Tech Lounge has a new review:
The Zen NX is really a great player for the money. It provides excellent sound quality when equipped with quality speakers or headphones and its large capacity should keep your listening repeat-free for days (and days, and days…) on end. If you frequently need to transfer files between computers, the Zen NX also serves as a portable hard drive, making it a very useful companion. I would definitely recommend the Zen NX to anyone looking for a portable player with large capacity. The hard drive makes it unsuitable for jogging or any activity where it will be subject to a lot of vibration, but when you are waiting for the bus or sitting on a plane it is very enjoyable to have around.
