I know I'll be picking up a GS4 after owing and S3 and being incredibly impressed. I wasn't going to upgrade until 2 years later but the Exynos 5450 and a 1080P 4.99 inch screen has me sold. So I certainly hope Samsung sticks with the curvy nature of the S3. It is by far more comfortable than all the other phones out there with sharper edges. I don't know if Apple will ever go back to the comfortable curves of the 3Gs but I for one would welcome it. So what do you prefer for your next device in terms of design.
