I got a Nook Color instead, since I primarily wanted a eReader that would support Adobe's EPUB format for digital library books. It has a lot of potential as an Android table if you make the necessary hacks to open it up. Obviously it has no potential as a chart plotter, since there's no GPS chip built in, and no apparent way to interface an external sensor.
I briefly flirted with an iPad instead, but it's about 3x the cost. I'm still not completely sure about my decision, though.
Because I sail on a river and do a lot of tacking, my Oregon 400c has been extremely helpful for deciding how close to shore to go before tacking. Based on the sailing I did last season, it seems to be VERY accurate for the area where I sail. It is so helpful that I'd consider spending more $$$ to get something with a bigger screen. I'm considering a GPSMap 640, but still wondering whether the iPad would be a better way to go.
As you can see by my pic below, my bimini will prevent direct sunlight, and I tend to avoid rain since we're daysailors. In the rare case of rain or splashing into the cockpit I could use my waterproof handheld instead - or consider one of the waterproofing options.
For those who have tried the iPad, how does its screen work outside? Is it bright enough to see in a shaded area? How is the glare? Does iNavX support course-up, or just north-up? Does any program out there support NOAA's ENC charts directly? (I believe iNavX is raster only.)
It turns out my son has iNavX on his iPad, so I tried it out a bit last night. We could not figure out a way to enable course-up mode (where the chart rotates, and the location indicator continues to point up).
One other option I can consider (instead of iPad or GPSmap 640) is to use my netbook with OpenCPN software (which does support course-up). I had some mixed results with that last year, but could try to optimize it to load charts faster, and fabricate a mount that could install at the top of my pedestal guard. My Wind U100 netbook has an extremely bright display that has no problems in daylight, and a non-glare screen.
