I work a lot of digital illustrations and have therefore been testing various graphics programs, and streaming software. Also goes great, I've found that I could work in theory in three different image processing software at the same time and the whole probably top of that stream still, without having to accept large performance penalty.
Of course, there are tiny quirks. The computer looks very dusty quickly by all the shiny surfaces, and from time to time can be a key press a little harder than usual. But all in all I previously had no experience with it that has really disappointed me. I'm very happy with this model!
