Oh nevermind. Metro apps won't work on anything lower than 1024 x 768. So yeah be wary if you want to test this out on an old netbook. Problem solved I guess unless anyone has a workaround for this. I might try an external monitor to try this out.
I just installed Windows 8 Dev 32-bit on an old Asus N10Jseries netbookwith a Atom N70 processor and 2 GB of memory. It runs the Metro UI even at 1024 x 600 resolution. However the Metro UI buttons for Metro apps do not work at all.
The only buttons that work are for normal Windows...
