I just called HP on Monday morning and explained that I was having trouble with the Shift key. Consistently, the key pressed after I press (<Shift>) was swallowed by the 100LX and the following key was shifted to uppercase (e.g. press (<Shift>) and key in Stanley, and Anley appeared).
According to HP, the problem occasionally appears in earlier versions of the 100LX, but many users of earlier 100LX's NEVER have this problem. The tech support person sent me a replacement unit -- no trouble, no hassle, just great service.
