There are no differences between iPAQ models ending in a 0 and 5 (i.e. hx2750 and hx2755). HP uses these different model numbers to track whether the units are sold via retail/consumer outlets or corporate. We had the hx2755 and it does indeed have the fingerprint scanner. Our review mentions HP's numbering convention: http://www.mobiletechreview.com/iPAQ_hx2750.htm .
