As for the size of this thing, yeah it is big but that is why I bought it. I have small chubby Man fingers but don't find it difficult to walk, read and scroll using one hand. When it comes to using the camera..seriously? How can you possibly have troubles with this? Look around at what others are doing when they use their smartphones whether it be an iPhone, android or blackberry, 90 % are using two hands because they are busy texting something. As I still own my old iPhone as well as an iPod touch, I find myself laughing when I pick it up..it's like a toy now..so small!
Finally, when making a call, the ear speaker at my ear and the microphone actually at my mouth, this is no different than using a normal phone on your desk or how things were with those original white motorola phones, but with the thickness less than an iPhone and half the weight...yes I loved the iPhone and the technology, but come on, this Samsung Galaxy Note is by far the best thing to come along..to date.
