Mio’s DigiWalker line of GPS units has two newcomers: the C523 and C525 models, which will release in Japan later this month. Both have Windows CE.NET 5.0, a 4.3-inch 480 x 272 display, 2GB of internal memory, an SD card slot for expansion, handle MP4, QuickTime, AVI, 3GP, ASF and WMV. Ditto for the C525, but add a built-in extendable antenna.

All available by September 26th for around $500.

Creative’s keeping mum on this new ZEN, but Amazon’s singing like a canary. Specs:

• 2.5 inch display
• 4GB, 8GB, and 16GB options
• FM tuner
• Voice recorder
•  SD slot
• Audio formats supported: MP3, WMA, AAC, Audible
• Video formats supported: WMV, DivX, MJPEG, Tivo to Go.

Pricing ranges from $149 to $299, depending on storage. They’ll be out soon.

Samsung’s been making some nice things lately, but what’s with the naming? The Yepp (Yepp?!?) YP-P2 is a lovely critter, and quite svelte: only 100 X 52 X 9.2mm. That’s thinner than a runway model… (I’ll leave it at that). Specs:

• Up to 8GB Flash storage
• 3-inch, 428 X 240 pixel touch-screen
• Integrated speaker and mike
• Integrated FM radio
• Integrated Bluetooth
• Plays MP3, WMV, WMA, H.264, and MPEG-4 (ASF)

No pricing or availability yet, but I imagine some folks will be hankering for this one.

Capitalizing on its return to (relative) fame, Commodore is expanding beyond computers with the Gravel C200 medial player. Beyond the strange name (Gravel?), it looks like a pretty mediocre device. First, it’s a little, well, not good looking, and has some unimpressive specs: 1.8 inch color screen, plays MP3, WAV, WMA, MPEG 2, MPEG 4, DivX, Xvid, and WMV (which is admittedly a nice long list), and is available with 512MB, 1GB, and 2GB models. Pricing and availability unavailable, but I’m not sure anyone’s going to be waiting that impatiently.
