Does anyone know anything about the video playback features of the EVO 4G? I'm coming from the iPhone where playback was limited to mp4 (encoded with h.264 or ffmpeg). Either way, this thing can supposedly handle 720p. Is a 720p mkv going to be possible on this thing or am I going to have to encode video for this and buy some special player? That's one thing about the iPhone i'm sure I'm going to miss -- the core functions like music and video playing are built into the OS and work rock solid. With android, are there going to be a bunch of odd video players to download and try?
