What are your favorite unexpected things about Surface?
JP --
If I can modify your question to include "the extent to which it is," my answer is:
It's a computer!! As the Spaniard says, "It's a tool, not a toy."
As you already know, it was a laptop replacement for my Ladyfriend, and survived a six-week trip around China without incident. It is now on its way to Dubai, but this time with the external battery.
As for me: It is a laptop replacement, as well. My excellent HP laptop now goes to my daughter. It also replaced my iPad, which I was using exclusively as a reader, nothing else. That now goes to one of my granddaughters.
I guess I'm a little surprised at how quick it is. The I5 and the SSD are a nice combination.
I could ramble on, but would be repeating others.
Regards,
Russ
