Lisa of MobileTechReview managed to get her hands on the Dell Axim X51v (http://configure.us.dell.com/dellstore/config.aspx?c=us&cs=19&kc=6W300&l=en&oc=X51624O) and has posted a first review (http://www.mobiletechreview.com/Dell-Axim-X51v.htm) along with a benchmark test comparing Windows Mobile 5.0 to 2003SE. As we expected, the Axim X51v is basically a blueprint of the X50v, except that it has double the flash memory (256MB) and comes lead-free to comply with European regulations. File access has become considerably slower due to WM 5.0 saving applications in Persistant Storage (ROM).

Some updates:
