Recently I have finally switched to a ThinkPad X41 Tablet for my everyday computing need. I said “finally” because I actually had the machine since more than a year ago (Sept 2005), but it had more than a couple issues that kept me from relying on it solely. I remember being asked on a trip why I brought two laptops along. 
The good news is that Microsoft has fixed two of my issues over the summer. If you are using a X41 tablet as well (already there are five in my group), here they are:
- Insufficient System Resources Exist to Complete the API during hibernation: hot fix 909095
- The mouse pointer or pen pointer behavior is irregular in Windows XP Tablet PC Edition 2005: hot fix 920295
The latter is particularly important since it makes the tablet a lot more responsive when the CPU is under load. I can’t imagine how I could have lived with a “jumpy” cursor for over a year…
Now if only someone makes a fast and reliable 1.8″ harddrive…

I have been experiencing the same “jumpy cursor” since buying my X41 Tablet this past Spring, and after installing the hotfix it is still having the same issue, just less frequently. Any suggestions on how to completely resolve this problem?

I’m having the same problem with mine… x41 seems to be really quirky….
