Dell has posted the data sheet (http://www1.us.dell.com/content/topics/global.aspx/corp/environment/en/prod_datasheets?c=us&l=en&s=corp&~tab=5) of the forthcoming Axim X51. Nothing new here and it really looks exactly like the X50 (size, specs), except for power consumption where the X51 seems to use more at maximum CPU usage but less in sleep mode.

Meanwhile on a Chinese forum, someone posted screenshots of the X51 (http://www.hi-pda.com/forum/viewthread.php?tid=273097&fpage=1) running WM 5.0. At least to me they look very legit.

Thanks to Marquard!

From the specs I conclude:

X51 = X50 + WM 5.0 Upgrade

According to a chat with a Dell Tech Support Agent the official release date of the X51 will be tomorrow, Monday, September 19, 2005. And it will come with a 256MB Flash ROM.
