I’m a mac guy so my interaction with Windows happens almost exclusively through Parallels. Hence, I was surprised to see that this Dell notepad can be turned into a multi-monitor workstation that presumably would run Xojo since it’s running the full 8.1 OS.

Presumably.
I don’t know enough about the Atom’s to know whether they can run normal x86 Windows apps out of the box or not but if they can then should be good to go.

The Atom is a full fledged x86 processor and will run Xojo just fine. My old Asus 1000HE with a first generation single core Atom processor does just fine and I expect a modern quad core will do as well.
