Kubuntu Focus Ar Gen 1 Laptop 4 / 5 Very good pros and cons Pros More than enough performance, even for AI. Cons Ships with the Kubuntu Linux distribution and starts at $1,950, which is a little pricy. I've tested Kubuntu Focus hardware before (such as the NX Gen 3), and they always impress. To experience that power, start opening several apps and you'd be hard pressed to watch the Ar Gen 1 stutter. There is really not much bad to say about the Kubuntu Focus Ar Gen 1 laptop.
