2.2 pounds. 3/4-inch thick. Big hard drive. Multiple batteries included. 1GB of RAM.

No modem. Three-cell battery has short life. Cramped keyboard.

Sansa seems to be turning back the clock with the release of its slotMusic Player. Does the world really need new music delivered on microSD?

Cheap, small.

Technology already feels outdated. No rechargeable battery. Cards are overpriced.

The pricey iriver Spinn suffers from a lack of grace and simplicity typically found in the company's standout players like the excellent Clix.

Interesting design and control layout. Robust file support, including lossless audio. Large, crisp screen, which is great for video and photo viewing. FM and voice recording.

Overpriced. Touch screen seems superfluous, and it's easy to overshoot your selection with the cylinder controller. User interface isn't all that attractive—and could be more responsive. Storage tops out at 8GB, and there's no expansion slot.

Question: What's the difference between last year's Zune 80GB, loaded with Microsoft's new free firmware, and this year's Zune 120GB? Answer: 40 gigabytes. Oh, and a glossy-black finish. Otherwise, the "new" $249.99 Zune is identical to its older siblings...

Wirelessly syncs to your PC. You can buy music wirelessly and purchase tunes you hear on the radio. Increased capacity. Large display. Touchpad is still excellent. User interface is good-looking and easy to navigate.

Too many steps required to play a song. Requires a $14.99-per-month subscription or prepaid MS points for wireless streaming and downloading.

Still the best hard drive-based portable media player on the market—the feature-barren iPod classic can't compete with the Zune's top-notch navigation and added wireless abilities.

Calling the Zune 16GB a new product is a bit of a stretch. With no real hardware changes, and the ability to load the new software onto any of the older models, we're basically looking at the same old player with a paint job, a capacity upgrade, and price...

Touchpad is still excellent. Improved user interface is less jumpy. Wirelessly syncs to your PC. You can buy music wirelessly and purchase tunes you hear on the radio. Unlimited radio presets.

Requires the $14.99 monthly Zune Pass or pre-purchased MS Points to download music straight to the player over Wi-Fi. No change in design, display size, or screen resolution from older models.

If you're a dedicated Slacker listener, the G2 is an excellent way to take your songs with you. If the company can iron out a few ease-of-use issues, this player could be part of a digital music model that gives Apple a run for its money.

Smaller, slicker, and less buggy than the original Slacker Portable player. Refreshes music automatically via Wi-Fi. Easy to create custom stations online. Player displays album art and artist bios. Also stores and plays your own AAC, MP3, and WMA files.

Software hits some snags. Wireless connections can be spotty. No photo or video support.

The Archos 5 offers oodles of storage, built-in Wi-Fi, a Web browser, and a big, beautiful touch screen.

Tons of storage. Sleek design. Huge, beautiful screen. Built-in Wi-Fi and Web browser. On-screen home button for one-click main menu access. No need for stylus.

Quite expensive. Power button is also the reset button. Touch-screen interface is not as sophisticated as iPod touch's. UI could stand to be streamlined a bit—requires too many clicks at times.

Apple's crown jewel player line gets slimmer, cheaper, and, uh, more fun.

Stunning, sprawling glass display. Access to App Store and iTunes Store via Wi-Fi. Built-in Internet browser. New Genius feature builds playlists for you.

Very expensive. Fingerprint magnet. File support is still extremely Apple-centric. Watch the iPod nano (4th Gen) and touch Video Preview!

Apple's slimmed-down, slicker-than-ever iPod nano responds to your movements, creates playlists it thinks you'll like, and makes the competition look like a bunch of clunkers.

Sexy, thin, rounded design. Same excellent user interface as in previous nanos. Built-in accelerometer shifts screen for horizontal viewing (like on the iPhone and iPod touch) and lets you shuffle songs by shaking the player. Genius feature creates on-the...

No built-in mic—you need to upgrade earbuds to use the integrated voice recorder. Apple still hasn't upgraded those lame bundled earbuds. Watch the iPod nano (4th Gen) and touch Video Preview!

The Creative ZEN Mozaic is the latest example of Creative's long-standing tradition of developing good-looking budget portable media players. The Mozaic comes in 2GB ($59.99 direct), 4GB ($79.99), and 8GB ($119.99) capacities, and its control pad, as its...

Very affordable. Good-looking, interesting design. FM radio with 32 presets. Voice recorder.

Unintuitive, clunky user interface. Included earbuds are subpar.

The Creative ZEN Mozaic has plenty of features for its price, but don't expect the cool design of the player to extend to its user interface.
