[oilisab]

As i can see so far they have the same hardware specs?? Both have 520mhz, 64 mb ram and 128 mb Rom.

Is tehre any special difference??

Yes, both are essentially the same, except the X51 features Windows Mobile 5.0, while the X50 features Windows Mobile 2003SE (though the upgrade to Windows Mobile 5.0 is expected sometime this month).

If you're referring to the X50v and X51v, then there are some slight differences - mainly the ROM size. I suggest you check out this review: http://www.pocketpcthoughts.com/articles.php?action=expand,43092
