This is a discussion of how to design a video website's UI based on a cell phone's features. I personally think that the UI should be based solely on the phone's screen size. A co-worker thinks that phones with more features deserve a more complex UI.
Consider our current design on the iPhone, which the co-worker judges as a weak phone. The channel listing is very simple. You tap a channel to play it full screen. Everything is similar to Youtube's app.
The co-worker wants to extend our website to Android phones, which he judges as a phone with superior features. Because Android phones have a multi-threaded operating system, this allows one to play videos inline rather than full screen. The co-worker would like to have the video playing inline with the channel list on the right. This would allow for a a faster channel surfing experience - you can change the channel without stopping the current channel.
My beef with this Android mockup is that the channel list text must be made smaller to share space with the inline video. I'm worried that the channel surfing experience won't be as easy as the co-worker thinks it will. I suspect people will have to pinch-zoom and pan the screen a lot just to read the channel list text.
The bottom line question is: should video always play fullscreen on cell phones, even if there may be features on the particular phone to allow it to play inline? And by phone, I mean a normal hand sized phone, not any crazy gargantuan phones that are coming out these days.
