DM42 early units vs. current?

[Dave Britten]

Hey Sylvain, sounds like we've had similar experiences, then. The missed/bouncing keystrokes were the reason I peeled up the keyboard and cleaned the contacts. It wasn't a perfect fix, but it's vastly better in that regard. It's strange that the Voyager lookalikes are so much better. They aren't quite at the level of real HP keyboards, but they're perfectly fine, enough so that I'm considering a DM15L just for the faster speed and increased memory.

Based on johanw's response, though, it sounds like more recent units might be a bit better than the early ones.
