I had a surface RT and sold it due to poor performance. This problem is all but cured in the Surface 2, the Tetra 4 lives up to the hype in my opinion it is blazing fast for an ARM quad core device. That being said the 2520 will likely be slightly faster due to the better processor (clocked slightly higher). Not sure this is a huge difference, but something to consider. Performance - Nokia Slight advantage
Design- Tie, I'd give the Nokia the edge here in pure sexiness and feel of the product, the Lumia design language is unparalleled in the electronics world IMO. However, the kickstand on the new surfaces is so on point and the keyboards really are stellar, sure it doesn't look as good as Nokia (albeit these devices are all top top notch sexy), but in terms of using the kick stand and keyboard is so great.
Connectivity - Nokia wins LTE, hands down winner.
Memory - Surface, expandable storage is more capable.
Accessories - Surface, type covers trump all.
Screen - Tie both sharp 1080P
etc...
The basic answer here is go to a Microsoft store and decide if you want to hold a surface 2 or a large Nokia Lumia 920 type device. The answer to that question is the one I would buy.
