It may just depend on the interface. My last car had a button interface that never felt intuitive. My new one has a very intuitive touch screen and I don't find myself spending any time looking at it.
Well, he still can. By exporting them outside Federation. Federation is a non monetary state, yes. But everyone else still conduct trade. Even in Bajor, Deep Space Nine still conduct trade. There are also several bars / night clubs in Star Trek universe. Quark will definitely welcome Picard's wine. The bar / nightclub in Picard season 1 will definitely accept, and Raffi husband can also become Picard's chateau regular costumer. Plus, Picard also has Laris, an Ex-Romulan Spy. So even if Picard is ignorant to Monetary sense or trading sense, Laris doesn't. I'm not sure that Romulan is also a non monetary state. They definitely conduct trade. Like Dominion also conduct trade. With those trade, Picard will definitely need one or two freighter, and if Rios can buy a ship like La Sirena, Picard definitely can buy a better one. So, in a sense of capitalism, Picard is basically not poor. He's rich. But of course, his richest will depend solely to the writers judgement. If they decide that Picard will only give his wine for charity, then that's it is. But in the universe sense, he has a lot of opportunity to generate profit, and buy a descent ship from outside Federation, like Rios.
That's why I said in my post. La Sirena is a product of capitalism sense, that they include cooler Holographic controls and EMH emergency feature in it. The Producer include those cool feature, because they want to entice their costumer to buy La Sirena. But USS Titan A is a product of a socialism government, who ignore cool features, and stick to old, proven feature, like a touch screen computers. An old, and outdated 24th century features. Just because they work as intended. So why change things when the old one still can work.
