It is, but the Axim isn't a Handheld PC - it's a Pocket PC.
JMaples, since this site deals with a different kind of device
(the Handheld PC runs the core CE OS, has a wide landscape display, and usually has a built-in keyboard
), you're less likely to run into someone here who is familiar with the X51v and can help. You're more likely to find help at a Pocket PC site like Pocket PC Thoughts or Pocket PC FAQ.
