I've done several searches and have read articles and other forums. However, I was interested in having as close to a real time conversation with folks who have recently had experience with the subject at hand as I could.. I was under the impression that's what forums were for.
I've been a long time member on numerous forums over the years on a variety of subjects, but I've never felt tiresome or annoyed by recycled topics, I simply scroll past and move along. Suggestion someone uses a search feature is fine, telling someone to "get on a computer" is a little rude, but I guess that's subjective.
The answers one gets to a question is directly related to the quality of the question. Ask a good question and you get a good answer. That was a lesson my research profs taught me in grad school. Some questions are just not answerable, some yield poor answers. A good question yields good usable information.
For new folks on this or any forum, putting a question in context goes a long way to getting good answers.
Your question as asked was not a particularly useful question and it won't yield particularly useful answers. It is roughly akin to the ever popular "what boat should I buy" question that shows up here and on other sailing forums almost every week.
As asked, your question does not indicate that you have done any research on your own or have given it any real thought. We have no idea how you intend to use the iPad (other than for navigation) or in what waters. What are your sailing and navigation skills, and so forth.
When frequently asked poorly formulated questions are presented, inevitably someone gives an answer that might be considered snotty. A good response to that snotty response is to reflect on your own behavior and why it might have prompted that snotty response. There are any number of decent respectful responses you could have made, a simple, "I tried to find the search function on the app, but couldn't. How can I search using the app?" Would have gone a long way towards avoiding scolding responses.
Instead of a civil and respectful response, you issued a condescending and insulting remark. Would you have said that to his face? With the kind of response you made, one might raise questions about your parentage.
Be civil, be respectful, and respond to comments and questions as if the person was sitting across the table from you. Do this and your experience on this and most other forums will be pleasant and informative.
If you prefer to be rough in your language and confrontational, might I suggest you head over to Sailing Anarchy.
