PocketNow has a review of the Dell Axim X51v, running Windows Mobile 5.0. Although very similar to the Axim X50v, the X51v does have some new improvements. Check out the review for the full story.
"The Axim X51v is Dell's top-of-the-line Pocket PC. It includes a 624MHz processor, an Intel 16MB graphics accelerator with OpenGL ES and JSR-184 support, and a 3.7 inch VGA screen. It's also got integrated WiFi and Bluetooth along with an SD card slot and a Compact Flash card slot. The only thing missing is a GSM/GPRS phone module. Oh, I almost forgot... the X51v includes an unprecedented 256MB of ROM! Since this uses Windows Mobile 5, all of the applications and data are stored in ROM along with the operating system. The 64MB of RAM is only needed for running applications."
