I've been thinking about downgrading from my SP2 512GB to the SP3 128gb version. I have a 128 gb microsd card for storing movies and games. I really want to know what the experience is like reading comics from the Marvel Unlimited app in portrait mode on the SP3? It is not a good experience on the SP2 due to the long form in portrait plus the weight. Does the SP3 feel similar to using a tablet like the ipad air? I don't use my SP2 when reading in bed because it just feels to much like a laptop versus a tablet. I'm not sure if that makes sense but wanted to see if SP3 owners feel it's a good replacement as a tablet for reading.
