1. Samsung does provide an alternate interface for Windows Mobile; it is not turned on by default though. If you go to Start, Settings, Today, you can enable the Samsung Today UI from the Items page. The alternate UI looks too kiddish in my opinion, but it is touch-friendly and covers many things like photo-contacts, missed calls/messages, favorite application shortcuts and other settings. It also has a large clock.
2. Launching the Camera application is as easy as pressing the Camera key near the bottom right corner of the QWERTY keypad.
3. You can assign your own MP3 ringtones. You need to copy them to "\Application Data\Sounds" first.
4. The Epix also has Wi-Fi, something I didn't see mentioned in the review.
