Fantastic impressions throughout !
My use case is 600DPI colour artwork duplex scanning, so can't comment on office document processing.
For me : phenomenal technical image quality of output, deep software capabilities and small physical footprint make this a winner.
Most interestingly as well, having owned two tray-fed document scanners before, I am extremely pleased by how little (if any) cleaning this Canon unit needs for persistently artifact-free 600DPI colour duplex artwork scans.
Fuijitsu ScanSnap and Plustek units I used before needed a clean every 25 sheets of paper to avoid dirt depositing on the two optical scanning elements.
For whatever magic reason this Canon goes through 150 sheets (and often a lot more) before any dirt artifacts begin showing in the final scans.
The service from TradeScaners guys has been fantastic, too.
Helpful pre-sale advice followed by the unit arriving when scheduled.
I'm happy !
