I'm currently using 4 phones...the Z2, S5, M8, and Note 3. I really only use two everyday at work and when I'm out, so the others get rotated in. I'm currently using the Z2 and the Note 3. No matter which new phones I get I can't seem to let go of the Note 3, the S-Pen is just a must-have feature for my work. Really love the Z2 so far though!
