Not a huge amount of new highways as Guildford is already well-mapped but there was a lot of guesswork, visual_estimates and inaccurate GPS traces in some areas. In particular, the imagery has helped me focus on cleaning up and rerouting many of the NPE-traced waterways in the region. Instead of flowing through industrial estates and over roundabouts, the rivers, canals and streams I've edited now flow alongside the accurately mapped towpaths/footpaths and under the bridges that others had carefully added! The imagery is great for adding/correcting other landuse/leisure areas; correcting parks, woods, golf courses etc. I've also used it to trace a few major buildings and add detail to car-parks and complex road junctions. The combination of high-res aerial imagery and OS StreetView data is very powerful indeed. For the sake of walkers and cyclists, I'd encourage others to tackle Surrey's waterways. The road network is fairly sane but the (typically NPE-derived) water network makes a somewhat confusing mess of the more recently and accurately mapped geography.
