WMPowerUser is linking to the CNet review of the Verizon Omnia, and overall it looks pretty good:
The good: The Samsung Omnia features a spacious touch screen with customizable Home screen, haptic feedback, and accelerometer. The Windows Mobile smartphone also offers Wi-Fi, GPS, Bluetooth, and EV-DO Rev. A support, as well as a 5-megapixel camera and robust multimedia features.
The bad: You’re still limited to the preloaded widgets. The onscreen keyboard is a bit cramped, and the Omnia can be sluggish.
The bottom line: Though slightly more expensive, Verizon customers looking for a touch-screen smartphone will get a better user experience and faster performance from the Samsung Omnia than the RIM BlackBerry Storm.
