I'm a huge fan of my SP4, I have the 16GB RAM, 256GB Storage, i7 model. Yes, ridiculously expensive. But I now spend 70% of my time on my tablet instead of on my desktop(i7, 16GB RAM, 780GTX, 2x1080p screens). I only spend time on the Desktop for gaming specifically, everything else including running VM's and developing, watching movies or reading, all work great on the tablet and the battery life lasts me all day at work, or all day at home, essentially exactly matching the expected performance. Runs older games fine for major titles, haven't tried newer games because why would I, that is what the desktop is for. I'm not sure I'd appreciate lower performance tbh, or lower storage. 256 is the minimum comfortable level for me to work on, the i7 keeps up with what I do but I think lower performance would actually be pretty noticeable. I probably could've been happy with 8GB ram, but no less.
