I just bought an iPaQ hx2490 today, I am guessing it's very similar to your 2495. A review can be found @:

Just to let you know, this hx2490 is designed and made by LG Electronics/Samsung, for HP! I find it quite nice but of course, the major difference between an Axim X50v/X51v is that the Axim has VGA resolution, whereas the iPaQ does not (unless you get the hx4700).
Just to let you know that the HP hx4700 is also designed and made by HTC Taiwan, the same company that makes Dell Axim X50/X51 series.
