So with about 48 hours of use so far, here are the main complaints I have; 1.) Stylus Storage. With other tablets, a stylus wasn't really needed, but with the SP there are some operations that are nearly impossible without the stylus - at least with my big fingers. The magnetic coupling is so weak that the stylus falls off all the time. I end up hunting in my backpack for it. 2.) The hard plastic case makes the unit slide. I was using it on the train this morning and with the kickstand, it slide all over the place. Some sort of rubber coating on the bottom edge would really help. That's about it. Amazing machine.
