Please forgive me my boldness as to firmly disagree with you.
Wind speed is nice to know, but no more than that. Wind speed is only good for bragging in the marina bar on how big a storm you've been through. The decision on the amount of sail one needs to put up (or down for that matter) is never
made by looking at a wind speed indicator. Also, knowing that the wind is picking up now
is simply useless compared with knowing in advance
if the wind will do.
The direction can easily be obtained from a simple wind vane
that is most probably on board anyway.
When used properly a barograph is very informative. I have one in my watch (Casio Pro-Trek) and it allows me to make (albeit rough) forecasts and shows nicely when the eye of a depression is retreating. One like OP has is on my wish list
It does however depend on your intended use. If you want to do some races maybe wind speed and direction (true and relative) are of more use. If you intend to make day trips and you can obtain forecasts easily a barograph might also be of little help as met-office forecasts are usually much better, further into the future and more scientifically rigorous. So keep that in mind as well.
