Well, as a long term owner of portables....
The cutting board top was a mixed idea... had to be regularly oiled, and if you used it as a cutting board, there were questions of contamination, cross-contamination, and cleaning the thing.
Couldn't detach it and put it in the machine.
I have had 6 dishwashers since 1973, and three of them were portables. The built-ins were in my first three apartments.
Frankly, I LIKE the laminate top on my current dishwasher. I use a dishwasher safe cutting board on top of it...nice height.
As for bling, you can look at the "designer kitchen" crowd...how they like appliances to be hidden. Not me. I like to see my appliances!
