Due to the small size of my desk (and my need for minimal clutter) — that served as my basis for looking for a scanner with a small footprint. My needs other than that were minimal; I wasn’t planning to scan photos or negatives, so actual pixel-by-pixel color accuracy wasn’t a big concern. So having size as my primary restriction, I was left with only a few choices. Among them, it was primarily between Fujitsu and Neat Receipts. The form was considerably more expensive, and the latter, although in the same price range, seemed to lack in the usability department (from others’ reviews).
As for the actual real-world usage of the Pentax DSmobile 600 scanner, I must say it’s been a great addition to my gadget collection. My documents generally scan pretty fast, get directly saved into a PDF, and I’m done. I’ve had no need to use the OCR functions yet so I can’t comment on those. But as for the size (small), and the lack of clutter (only 1 USB cable going to my computer) — the product just fits the bill.
One thing that I have noticed is that since the paper is fed through by rollers, there have been instances where one size of the paper is fed into the scanner first, causing a mis-aligned output image. That’s not much of a problem since it can be remedied by scanning it again, but it is sometimes frustrating when you are in a hurry to get something scanned and are naturally getting lazy about feeding the paper into the scanner optimally.
