Surface Pro Owners: May i have your honest opinion?

Hi folks,

so i was just about to hit the "buy" button for a brand new Samsung Series 7 or Series 9 Laptop when i saw the expanded availability of the Surface Pro (Germany here).

Now i'm not sure if i should go for the Pro or still buy a Samsung Series 7/9 (7 prefered so far).

I know the specs of the Surface are a bit lower (RAM, Storage, CPU, (GPU)) and thats where you guys come in:

In your honest opinion: can the Surface Pro replace a laptop/ultrabook? I work on desks, on my lab, on the couch - i don't do video-editing on my laptop but a little photoshop should be lag free.

Can you recommend it?
