Well, it's a lot more than minor changes to the interface - yes, there's a new colour scheme. There's also better english throughout, and more consistency too, so none of the different styles of window that pop up on the TF5800.
In fact, the list of timers does show programme names, as you can see from the screens I posted yesterday over on Toppy.org.uk; in various regards, the manual is not up to date with the latest firmware. And, of course, that particular change is one that's coming to the TF5800 too.
Personally, I think the new interface is a massive improvement over the old one, with all its rough edges. I'll probably post some more grabs from the 5810 over the next few days.
