@blacklight I agree with your point - and we're even in a worse place with the web taking over the app space - even more fragile and needs a browser that's eating half my memory...
BUT, it does have to be noted, the Voyager software is absolutely single purpose, very tightly crafted, minimalist, engineered into the ground at high cost and sold to exactly two customers (Vgr1 and Vgr2) and no one else.
So comparing it to wide audience tools running on a general purpose OS is a little unfair.
