For what it's worth, I use the Nobletech VNS system and have never had a bit
of problem with it. It runs on a Dell laptop with plenty of power and lots
of memory. I think graphic programs like this need a lot of memory, and most
problems you'll have with them are due to insufficient memory and computer
power. The whole rig is fed by GPS data from my Raytheon chart plotter, but
can also be switched to receive data from a small Garmin handheld GPS in
case of emergency.
I like the vector charts, which, to me, are much easier to read than the
often-blurry scanned raster charts on programs like The Capn, which I also
own and have used (and which also works just fine for me -- I just prefer
the vector charts).
Of course I also use paper charts, and keep real-time track of my position
on them. But the chartplotter/computer/GPS combo is handy if you get lost
AND is a pretty good way to keep you from accidentally venturing into shoal
water.
At least that has been my experience. Never used it on the Tenn-Tom system,
though.
