how do you want to reach compatibility to win7 application base on 32bit arm device?
obviously the device in question is surface pro, whatever version. it is a touch device with a reasonably large high resolution screen and pressure sensitive stylus, an i5 processor, good expandability through wlan, bluetooth, usb3 and few other options and win8. the drawback is low capacity internal ssd. but all in all very dependable device with good backward compatibility. im writing this from surface pro 1 i own since more than a year and am using underway for all my computer tasks like digital imaging or compiling amiga stuff under vmware debian.
