Thanks…I appreciate that!
I use a 24" 1920x1080 for RT on my existing desktop, and I totally agree that resolution works well. That machine unfortunately needs to remain full-time Windows for business reasons, so all my Linux activity takes place on my laptop, which means various other tools like DT live on my laptop only. Hence the hunt for a suitable laptop to replace my little 11" 1366x768 machine!
Maybe I’ll stealth-install RT on a UX305CA in a Best Buy and see how I like it. 
The other machines you mentioned aren’t available here in Canada either.
