I got a 265wt for christmas this year and I think it's great. I doesn't have the lane assist, but it does sometimes tell you to keep right or left before you get to a tricky spot. The maps are great even in screwey Boston, and it's never told me to go the wrong way down a 1-way. It routes me around traffic too.
The traffic information is sometimes delayed, and the preloaded POIs are out of date as many restaurants listed closed years ago. The numbers are listed though, so you can call before you start driving
The only way it could be better is if it could access real time weather maps, news, traffic cams, internet through a bluetooth connected smartphone.
