Eddie - Of course opinions will differ, but I do think it's worth it. The touchscreen is very easy to use, searching/inputing is much faster, the GPS calculates faster, memory is much cheaper/bigger, screen has better visibility in various lighting, whole unit is smaller/lighter, etc. The unit comes with an AC adapter for home/hotel use (I always pack mine, as I like to plot routes at night!) and I have not missed a battery feature at all. The BMW version of the 2610 has a battery pack as an option (there was a post about this awhile back) and it is possible that option would work with non-BMW 2610's.
However, anything is better than getting lost :? and either GPS would add a great deal of relaxation and enjoyment to your next trip!
