  2. Requires manual synchronization step between layout and schematic via netlist.
  3. Software does not ship with pre-defined content; users may develop their own.
  4. Vendor website claims your Gerbers are free after first order "for a limited time."
  5. Parts list report, not usually acceptable as a proper BOM.
  6. Available in schematic tool only as an add-on from Value Added Reseller, not from tool OEM.

"The improved Parts and Display panels in the new version are really good.  This is a nice improvement in PCB123.  Also, being able to see the symbol/footprint of a part is a great feature.  On the Display, being able to center on the location of the board by d-clicking is huge!  The User Preferences options that have been added to the Edit Panel are intuitive and work well."
