The personal-organizer scanner space on the Mac has been fairly quiet since the departure of the Visioneer PaperPort from the platform (we miss you, guys!), but one of the leading new vendors is coming over to the Mac -- NEAT Receipts for Mac is here at the show and will be shipping later this year. NR's slim scanner and software bundle lets you scan and organize all your paper receipts on your computer, keeping records for expense/business and tax purposes without the clutter and mess.
The final pricing and availability for NR Mac isn't published yet, but what I heard at the booth is $180/$80 (with the scanner hardware or software only) shipping in Q2; you can use the software in standalone or watched-folder mode with most other Mac-compatible scanners. If you've got an envelope full of paper records that need the scanning treatment, check it out.
