How about the new ones announced today? They're pretty nice. I still can't stand Windows though...
I don’t see the hardware today really making a big difference if one is weighing this decision. The previous Surface Pro hardware was already pretty nice. IMO, the Surface Pro is a better laptop style device than tablet, primarily due to Windows and the new Pro X is a nicer tablet but is still hampered by the tablet software experience of Windows.
I found the new Surface Laptops to be the most impressive..what I wish Apple did with the MBA line.
