I had Motorola’s built-in Swype (version 3.5.something) on my Defy+ and installed this. For me as Scandinavian, the biggest difference is that the letters Ä and Ö are better positioned (closer to their QWERTY positions now than in the built-in). That aside, overall it feels like a polished version with slightly better accuracy. The latter’s hard to prove without long-term testing, but I was convinced enough in 15 minutes with the trial to buy the full version.
