Logos on phones
Confession: I don't think logos on phones are that bad.
I actually love the logos on my Sony Z1s. They're well-designed, and the one on the front of the phone helps me figure out which side is the top. The Xperia a T-Mobile logos on the back also look nice. And, as a person that likes Sony as a company, I don't mind them advertising. If I really wanted to, I could pull off the screen protector that has the logos on it (why don't all companies put their logos on screen protectors?!).
Some logos are uglier than others. I think Samsung's logo is actually quite nice, isn't obtrusive, and fits well at the top of the phone. LG's logo, on the other hand, looks horrible. The picture/name combination just looks bad to me. I don't mind it on the back of the phone, but on the front, it's ugly.
The Verizon G2 just makes me want to throw up. Not only does it make the device look lop-sided, the logo itself lacks balance. Just "Verizon" without the check mark would look so much better.
