Query: Nifty Mobile Scanner

Nifty mobile scanner for those who take their laptop on the road for business. Not a substitute desktop scanner, but nifty as a small, portable scanner in the field for visiting customers, trade shows, etc. TWAIN driver a little limited in some respects with respect to file formats (seems to be designed for Adobe PDF) but overall a small, lightweight and reasonably good image. I scan a lot of B&W documents in my business, so scan times are a little faster than for color, but both are reasonably fast for a scanner this size. Paper feed seems to pull docs through straight, if not crinkled. Pentax provides sleeves for scanning photos. TWAIN driver and software reasonably easy to install, although Windows XP directions and updates were difficult to find on the web and found on the VISTA compatible driver page of their web site. Would like to see this scan engine come out with a duplex version someday, but, for now, this fits my needs on the road and I'm glad I bought it!
