I think the next step in MP4 players will be cell phone integration, i just got 5 different models in stock and this is the first review of the iTB5 MP4/PDA/Cell Phone.
I am really amazed by this product, its nicely designed, like a Dopod/O2 XDA, a large 3" touch screen, i am not sure what OS it uses, but its nicely designed and has many features.
The video player is stunning, it comes with a clip from Matrix 2, video playback is smooth, the clip has a lot of fast movement. The sound is great, the player has two Yamaha speakers on the back, that provide good quality audio.
The only downside to this is that the battery life, with it being a MP4 player, cell phone and pda, the battery only lasts for about 4hrs when being used, however on standby the battery lasts about 100hrs (i left it for 3 days and the battery still had 1/4 left). Good thing is that the package comes with two batteries.
It does have a 1.3 mega pixel camera on the back, it can take pictures and record video. It has only 64mb internal memory, but you can add upto 2GB micro SD card.

Below are two stock images of the white player and the back:
I will post the others up when i have more time
