Our business is more hobby than work as we still consider ourselves retired, I just still needed the occasional fix according to my wife. But we don't even look at anything business, including business emails, until after dinner and generally check the emails in bed. We call if necessary but they don't call us on business unless an emergency, so haven't. Now we do talk to them on a personal basis as our key people are our best friends. We will occasionally sit in remotely on a Friday morning meeting. Other than that, we occasionally (once a month or so) will do a one day project for my previous employer. We'll do that from wherever we are. We can also access everything remotely.
We do have satellite capability as we are creatures of the technology age and being disconnected just isn't something we deal with well. However, I'd say we have WIFI that works decently perhaps 65% of the time we're docked. Also, very few times we're docked and don't have cell coverage.
We could deal with being out of touch business wise or not even having a business, but I don't think we could deal well with being out of touch with family (technically not family but we consider them to be) and friends. We're addicted to internet and phone. We admit it. Most nights we'll call one of our family/friends and just see how they are and what we're missing.
I know people say sometimes that they boat to get away from these things, but we'd really not like being away from it all. I think perhaps it's generational in that some consider email and phone to be an imposition on their pleasure. We consider it in a positive way as it allows us to stay in touch. We've had cell phones and internet our entire adult lives. I know we wouldn't enjoy cruising as much without them. We very much look forward to emails at night and seeing what everyone is up to. Oh, and we do skype. Last night we got to see our beautiful niece who we were in SC for her birth in August. So wonderful to still be able to see her and her parents.
I think to us the key is just knowing we can be reached and we can reach everyone else. And, of course, we bank, we invest, we do everything online. We do have scanning and printing capability with us as well.
