Personally, I'll go out on a limb here a bit, maybe but, be I proven right or wrong, I think both the Windows8 phones & the Surface (especially, the Pro) will be impressive.
HTC Windows Phone 8X and Link Removed look more aesthetic. But Ativ S is not bad either. am looking forward to the release of these Windows Phone 8 devices, Microsoft is holding an event on October 29 to launch Windows Phone 8
