Still Old School
Had the opportunity to borrow an iPad for a couple weeks and it was really, really cool. Not really into game playing but wound up playing one of the war games and was hooked. It's a really neat item because of the form factor and the touch screen.
One thing I noticed, though, it did heat up when game playing. Granted, some games are a heavy resource user. Solitaire probably not so much. Electronics don't like heat so if what ever one uses causes it to heat up just make sure it has enough cool air to negate the heat. Fortunately for us here we have yet to reach 75 degrees this year. The rain tends to have a cooling effect.
With regard to navigation, though, I'm still old school. Read: "paper charts". I always have charts along. I've been burned a couple times with the electrical system not working properly and wouldn't you know it, at the worst possible time. As they say in flying: "trouble comes in bunches", and it does.
Posted once before about this guy single handing in his Baba 40 from Hawaii to Alaska when a few days out - no turning back - his coffee cup spilled over on his laptop. And guess what he was using for navigation? Yup, now it was toast. Had all his eggs on one basket, or almost. He had just got his ham licence before leaving Hawaii and thanks to it he was able to get weather forecasts and other information.
Based on personal experience and others, I would suggest using any electronic navigation devices as a backup to paper, not the other way around.
If it was me and I had an iPad, which I would like, it would stay down below except for, say, when a more complicated navigation situation arrose. And that tends not to happen very often.
Also, maybe I'm not your average sailor because I'm just not hung up on having go have the latest gadget for use with navigation.
The other thing I would do is to run it off a true sine power source and not a modified sine source. There's too much money involved and if one has a lot of personal files you certainly don't want to loose them to a glitch. Lesson learned: Back-up your files!!! And don't ask me how I learned this lesson!
