So in my pre-purchase testing sessions of the rMB, I've been toying with apps that let you choose screen res options not available by default. I'm a fan of getting as much screen real estate as physically possible, (I've been one of those people who bought 17 inch MBPs until they dropped them.) I have sharp eyesight, so I found that I was pretty OK to work with the rMB even as high as 1920x1200, despite the 12 inch screen. Wouldn't always use it at such high resolutions, but found it perfectly fine for certain situations. So far I've only tried "switch res x", it was the first app I found which was free to try out.. Installed it temporarily on an in-store rMB and it seems pretty good. Does anyone have real experience with using 3rd party res switching apps? If there's one out there which is generally considered the gold standard, then I'd like to know about it so I don't waste time messing around with sub par or buggy ones when my rMB arrives. Most important to me are: a well-designed control panel UI, stability, minimal CPU/GPU penalty, minimal impact on battery life and a reliable developer who squashes bugs quickly and keeps up with OS updates so the app is always on point. Don't mind if the best one costs a lot more, just really don't want to waste time with any dodgy ones... Cheers!
