I can think of no other way to share with friends and family, the trip we've just done from say, the US to Tahiti, than pulling out a chart with all the notes, course, weather, etc. and laying it on the table. That alone is worth a chart table/nav station. Every trip we do over 200 miles has a chart marked and I still have all of them. It's hard to do this on a chart plotter especially when all the folks have to crowd around the back of the wheel to see it.
Then it's about the ritual of calculating the "day's work" and the excitement of seeing the destination approaching on the chart, taking weather reports (and making notes), running GRIB files on the computer, talking on the SSB to the available sailing net, filling out all the paperwork we'll need at the next port, checking electricity used through the night, filling in the ship's log for the previous watch, updating a blog, the list goes on.
Yes, you can do some of this from a sofa but really? If anybody on my boat seriously suggested getting rid of all that, they'll not be invited back.
And besides, if I'm going to enjoy a few drinks with friends and family, there's no place better than on deck. Sunsets viewed from the bar down below are nowhere near as good.
My nav station is definitely not obsolete.
