According to Phoronix, the demo of a Windows app running on Android was "horrendously slow," but Julliard chalks that up to the fact that the sample was chugging along on an Android emulator.
Julliard has led development of Wine since 1994 and is an employee of CodeWeavers, which sells a proprietary Windows emulator based on the open source software. It's hard to imagine running a Windows application on an Android smartphone, but it might make sense for tablets—or Android-based PCs and thin clients. (There are already ways to run Android apps on Windows.)
Wine on Android is not entirely surprising, since Android is Linux-based, and there was already a project to bring Wine to ARM processors.
"While Wine is coming to ARM and there's quite a lot of interest there, CodeWeavers is quite interested and hopeful for the success of Intel x86 Atom CPUs for tablets," Phoronix founder Michael Larabel wrote. "If Android gains traction on x86-based tablets and other mobile devices, CodeWeavers has a lot of commercial opportunities for pushing the running of Windows software on Android."
