I love Wimbledon! One of the only things I ever watch on the BBC channels.
I take your point about the button select channels but when I do that it shrinks the screen (unless that's my TV!!) so I appreciate having two channels to be able to choose which of the mainstream televised matches I watch and can switch between them depending on who is playing and how interesting the game is.
Some fantastic tennis games already and still in week one. Just a matter of personal taste though, I don't really watch anything like football, F1 etc... but love the two weeks of Wimbledon.
