If your system uses older PS/2 ports, the first model offers more flexibility. Both rely on wired connections for stable input. You do not get wireless freedom with either device. The dual-interface capability of the first model is a distinct practical advantage for varied setups.
Physical dimensions
Size matters for your desk space. The A4tech Left-Handed Ergonomic Keyboard measures 18.72 inches in length and 8.1 inches in width. The A4tech Ergonomic Left-Handed Wired Keyboard is slightly smaller at 18 inches long and 8.25 inches wide. The first model is longer but narrower. The second model is shorter but wider. The height is nearly identical for both. You should measure your available desk area before deciding. The slight variance in footprint may affect how the keyboard fits with your mouse placement.

Neither model offers significant heft for stability against heavy typing. The near-identical weights mean you can choose based on other factors without worrying about stability or portability.
Multimedia hotkeys

The second model shares the same core functionality. You get the same shortcut capabilities regardless of which unit you select. This spec is a tie for both products.
