My only beef that I've had with the save importing, is that the cyber-eyes I had in ME2's FemShep didn't translate over, even though they're the same texture that the Illusive Man has for his eyes.
'Course, I did some savegame editing to do that on PC. I'm certainly going to try using my xbox 360 controller with ME3. Hopefully, it's got the same seamless transition between controller/mouse and keyboard that Skyrim did.
I'm a bigger X-Strike fan than you.
