Both scan a signed page. Only one of them fits in a laptop bag.
Verdict
If you print anything at all, buy the all-in-one; the portable scanner is a second device, not a first. A compact laser multifunction scans faster, feeds multiple pages, copies, and prints the disclosures and contracts you still need on paper. The portable scanner earns its place in a bag, for the closing table and the kitchen table, where carrying a printer is not an option. For most agents the honest answer is that a phone scanning app covers the mobile case adequately and neither device is urgent.

You sign paperwork away from the office and want a clean flat scan rather than a photographed page at an angle. The DS-640 runs off the USB cable with no power brick, which is the feature that makes it genuinely portable. It feeds one sheet at a time, so a twenty page contract is a chore.

You have a desk and paperwork arrives in stacks. A laser multifunction with an automatic feeder turns a signed contract into a PDF in one pass, prints duplex, and copies identification without a second thought. Toner lasts far longer than inkjet cartridges, which matters if the machine sits idle for weeks between bursts.

For a few pages, usually yes. Modern apps deskew and sharpen well and produce acceptable PDFs. Where they fall down is a long stack, a page that must be perfectly legible, and any workflow where the file has to look like a scan rather than a photograph.
Less than you did. Electronic signature is standard for most transaction documents, but some disclosures, notarised items and older institutional counterparties still want paper, and that requirement is set by your broker and by state practice rather than by preference.
Laser for an agent, in almost every case. The output is text, the volume is bursty, and inkjet cartridges dry out when a machine sits unused for a month, which is exactly what happens between transactions.
