Rahasya,  you are wrong.
Surface comes in two flavors
RT and Pro
- RT is stripped down version of Windows 8 Pro
- Pro is the full version of Windows 8

And surface is available on both flavors.
Microsoft Surface with Windows 8 Pro has Intel Processor than ARM on RT.
Check their site out, microsoft is selling it online.
