Congratulations on the purchase, Lauri! I am a non-case kind of guy but dedicate my left trouser pocket exclusively for my phone. I tried a case for a while but didn't like the extra bulk.
I did put one of these anti-glare screen films on which is great and completely eliminates the finger smudge issue.
