I have to say I am pretty impressed with the 2535 live so far. Only used it twice so far and no traffic to deal with so not sure how the HD Traffic is but so far I really like it. I have the Nuvi 2460 too for about 2 months and I think I may try to sell it and keep the 2535. It's just all the little things on the 2535, like POI's on the screen and some with the Company Icon (i.e. Mcdonalds, Perkins, Dairy Queen, Subway, etc.) and choosing which poi's show on screen, pretty neat how it will speak the weather report, being able to turn zoom on and off on either 2D or 3D view separately, more streets seem to show longer when zooming out, I love how you can switch between 2D and 3D right on the map, there's just to much to remember there is definitely more to customize then any Nuvi I've had. The magnetic mount works really well.
One thing I would like to see changed is when you do a Google search it would give you a list of categories to choose from like on the internal poi search instead of just typing something to search for. Also would be nice to tap on a poi on the map and see what it is.
I think a long time Garmin user is now TomTom fan.
