Hmmm... Frankly the 620 seemed better to me. I'm reading reports on washed out screens on the 625 and not great contrast. The 620 screen has always been good and costs around $200, that's a full $100 less than the 625 - not worth the extra money just for a bigger screen that isn't good. I was doubting between the 620 and the 720, but the 720's screen and camera are much better than the 620, so I guess my decision has been made! I wanted to see how this 625 was going to turn out... now I'm sure I'm getting the 720.
