Couple things I don't like about my new Samsung A940.
1) When you close the lid, any running applications (web browser, text messaging) exit. My Sanyo would keep those running until I pushed the End key.
2) When you get close to 200 text messages in your inbox, it will warn you that it will delete old messages once it gets past the 200 limit every time you get a new text message. I know that, just delete them like the Sanyo did.
3) Garmin Mobile doesn't work on it. Not that I really care, Garmin Mobile is a garbage app anyways, it was just cool every now and then.
I do like the better camera (2.0 MP), EV-DO, bluetooth (works like a champ) and the business card scanner (very cool)
