The only slight prob I fond with the Pronto is unless you want more than one panel you have to have a cramped screen. Why not just have 2 main screens for constant use then have a hidden screen or two for the features that are not used as much. Thats what I have done and I found it works well.
Don't have Sky+ (yet) but I would imagine doing something along those lines would work well.
Only prob with RMC.com is just about all the B&W ccf files are just the same as all the others, with everyone using the same buttons/graphics.
Anyone else know of any other sites that offer downloadable ccf files?
