Any review of the Galaxy Nexus will note that it's huge. I like it. I'm 6'2" and this phone is great: it's much easier to type on and I can see much more content.
In the photo above I'm holding the Galaxy Nexus and my wife is holding her iPhone 4S. My phone is smaller relative to my hand, which leads me to conclude either:
a. The iPhone is too small for me
b. The iPhone is too big for her
She says (b), as she can't fully use the phone one-handed. I can use my Galaxy Nexus just fine, so it seems (a) and (b) are both true. Regardless, anyone who argues that the 3.5" is ideal must have ideal hands.
I was going to write a Galaxy Nexus review, but got distracted by the previous post. I fear that two posts in one month is all I can manage right now
