Dude you have no idea what you're talking about. The iPad specifically has almost single-handedly revolutionized general aviation. If you went down to your local small or medium general aviation field, you'd find that virtually everyone was familiar with ForeFlight, Garmin Pilot, or WingX, and that many of them were actually using it.
I am going on a short flight today in my little plane, and will be using my iPad Mini as my moving map. Foreflight is truly amazing for what it does, and for $120/yr subscription replaces literally $10k worth of cockpit avionics. Oh, and it is extraordinarily reliable and well-made. At the time the iPad and Foreflight combination came out, those "specialized tools" you mentioned had 4" resistive touch screens, required 12V power, and had horrible user interfaces. The iPad is better hardware than any of those devices at literally 1/5th the price, so all it took was someone to write the code for iPad hardware instead.
Commercial pilots and some charter ops use it (with the moving map disabled) as an electronic flight bag to replace enormous amount of paper charts.
These apps are not gimmickly little programs written in an afternoon by a teenager but expensive, well-written, and reliable commercial solutions. They work extremely well.

This commercial isn't trying to sell you an iphone because it is widely used in aviation -- it's trying to sell you on how many different people have taken the iphone/ipad and adapted it for their specific field. I don't know what you do for a living, but perhaps you can find a similar niche.
