For that price, I wouldn't find the 2520 particularly compelling, considering you could find other tablets for less.
For general web browsing, most tablets will suffice. (heck, my dad is happy with a last-gen Lenovo IdeaPad Lynx with a lower performance CloverTrail Atom) The Surface 2 had a $200 sale or so recently. There are relatively solid Atom tablets for the same price area, although they might not have quite the same fit and finish as the Surface/Lumia. (as well as an official keyboard option)
8 inch tablets are available if you so desire.
Off the top of my head, similar tablets worth looking at:
ASUS Transformer Book T100
Microsoft Surface 2 (especially)
Surface RT/1 (performance is best described as OK, but sometimes "ehhhh")
Dell Latitude 10 and other older tablets.
